As seen from Earth, the group lies near the plane of the Milky Way (a region sometimes called the Zone of Avoidance). Consequently, the light from many of the galaxies is severely affected by dust obscuration within the Milky Way. This complicates observational studies of the group, as uncertainties in the dust obscuration also affect measurements of the galaxies' luminosities and distances as well as other related quantities. Moreover, the galaxies within the group have historically been difficult to identify.

Darshanavarana karma or the perception-obscuring karma are of four types:Glasenapp, Helmuth Von (2003) [1942] pp.7-8 #chakshur darshanavarana-karma which produces the obscuration of the darsana conditional upon the eye, #achakshur darshanavarana-karma which causes the obscuration of the undifferentiated cognition, conditional upon the other senses and the organ of thinking, #avadhi darshanavarana-karma which causes the obscuration of the transcendental undifferentiated cognition of material things, #kevala darshanavarana-karma which hinder the absolute undifferentiated cognition (the counterpart of the omniscience). The last mentioned karma hinders completely; the three others produce under certain circumstances only a disturbance of the respective cognition faculties. In addition to these four darshanavarana karmas there are five others which produce physio-psychological conditions in which the sense organs are not active, and which, therefore, exclude all possibility of perception.

At Harvard College, the obscuration was reported to arrive at 10:30 a.m., peaking at 12:45 p.m. and abating by 1:10 p.m., but a heavy overcast remained for the rest of the day.

When converting luminosity or absolute bolometric magnitude to apparent or absolute visual magnitude, one requires a bolometric correction, which may or may not come from the same source as the color–temperature relation. One also needs to know the distance to the observed objects (i.e., the distance modulus) and the effects of interstellar obscuration, both in the color (reddening) and in the apparent magnitude (where the effect is called "extinction"). Color distortion (including reddening) and extinction (obscuration) are also apparent in stars having significant circumstellar dust.

Sagamore Hill Solar Radio Observatory is a functional component of the Radio Solar Telescope Network (RSTN). In 1980, he developed and published an auroral echo-scattering model to predict the obscuration of targets when the radar transmission path is through the auroral region.

Jñānāvaraṇīya karma or the knowledge-obscuring karma are of five types: p.6 #mati jnanavarana-karma which causes the obscuration of the knowledge, transmitted through the senses, #shruta jnanavarana-karma which produces the obscuration of knowledge acquired by interpreting signs (i.e.words, writings, gestures), #avadhi jnanavarana-karma which hinders transcendental knowledge of material things, #manahparyaya jnanavarana-karma which hinders transcendental knowledge of the thoughts of others, #kevala jnanavarana-karma which obscures the omniscience inherent in the jiva by natural disposition. Of these, the last mentioned karman hinders omniscience altogether; the four others do not result in complete destruction of the corresponding faculties of knowledge, but often produce only greater or less disturbances.

The wall measures over 1.37 billion light-years in length, and is located approximately a half billion light-years away. The massive structure extends beyond the Milky Way galaxy, in the Zone of Avoidance (or Zone of Galactic Obscuration),NOTE: "The 'Zone of Galactic Obscuration' is, simply as it says, an area of the sky where the hub of the Milky Way galaxy itself makes observations very difficult by obscuring what is going on. This is defined purely by our location relative to the galactic hub, and is not an actual object in itself." from the Perseus constellation in the Northern Hemisphere to the Apus constellation in the far south. It is so large that it greatly affects the local expansion of the universe.

The eclipse took place in Northern Antarctica and the Pacific within the 180th meridian and the International Date Line. In Antarctica, it showed up to 1.3% obscuration of the sun, it showed up to 2.3% obscuration in the Pacific offshore. The greatest eclipse was in the Atlantic off the shore of Antarctica some 25 miles (40 km) south of the Antarctic Circle at 66.8 S & 174.5 E at 11:58 (11:58 PM local time the same day). As the moon moved towards the right on the Moon, in that part of Antarctica north of the South Pole at the 180th meridian, it was seen as it was moved towards the right as the axis spun at around the 66th parallel south.

The Milky Way creates a Zone of Avoidance for local observers. The Zone of Avoidance (ZOA), or Zone of Galactic Obscuration (ZGO), NOTE: "The 'Zone of Galactic Obscuration' is, simply as it says, an area of the sky where the hub of the Milky Way galaxy itself makes observations very difficult by obscuring what is going on. This is defined purely by our location relative to the galactic hub, and is not an actual object in itself." is the area of the sky that is obscured by the Milky Way. The Zone of Avoidance was originally called the Zone of Few Nebulae in an 1878 paper by English astronomer Richard Proctor that referred to the distribution of "nebulae" in John Herschel's General Catalogue of Nebulae.

Two of these aircraft were modified with a Forward Looking Infrared (FLIR system) under project Lonesome Tiger, as a part of Operation Shed Light.Volume I Operation Shed Light Study Report, 1966. Their subsequent re-designation is lost to the annals of yesteryear... and the deliberate obscuration of the 'Black Community'. pp. 1C-55, 59.

Parts of the western Antarctic Peninsula experienced nearly 90% obscuration of the Sun. The eclipse belonged to Saros 123 and was number 53 of 70 eclipses in the series. This was the last of four partial solar eclipses in 2011, with the others occurring on January 4, 2011, June 1, 2011, and July 1, 2011.

The eclipse started at sunrise offshore from New Zealand and ended at sunset in a smaller part of southern Africa. The greatest eclipse was in midcentral Antarctica at 75.8 S and 1.4 E some kilometers from the Prime Meridian at 16:25 UTC The duration was 6 min 15 seconds and showed 91.5% obscuration of the sun.

Automated airport weather stations do not have a separate sensor for detecting specific obscurations to vision. Instead, when visibility is reduced below 7 statute miles, the system uses the reported temperature and dew point to determine an obscuration to vision. If relative humidity is low (i.e., there is a large difference between the temperature and dew point), haze is reported.

Big Bear Solar Observatory (BBSO) is a university-based solar observatory in the United States. It is operated by New Jersey Institute of Technology (NJIT). BBSO has a 1.6 m clear aperture Goode Solar Telescope (GST), which has no obscuration in the optical train. Light corrected by adaptive optics is fed to either the visible (VIS) or near-infrared (NIRIS) spectro-polarimeter.

The total phase of eclipse will be only in Siberia in Russia. Large cities, in which the total phase will be seen, include Yakutsk, Neryungri, Mirny in Sakha Republic and Khatanga in Krasnoyarsk Krai (also Norilsk will have 98% sun obscuration). As a partial, the eclipse will seen mostly in Europe (except for south of Europe), mostly in Asia and on the east of Greenland.

The motion of the shadow was supersonic and it generated gravity waves that were detectable as disturbances in the ionosphere. These gravity waves originate in the thermosphere at an altitude of about 180 km. Because of the obscuration of solar radiation, the ionization level dropped by 70% during the eclipse. The eclipse caused a 1–1.4 K drop in the temperature of the ionosphere.

Additional active protection can be provided for shaped charge warhead attack using Rheinmetall's Active Protection System AMAP-ADS. A range of passive protection and defensive aids are also available. They include a rapid obscuration system (ROSY), laser warning system and acoustic shot locator system. These are integrated in the Lance turret when it is fitted along with automatic target recognition and automatic target tracking.

In its eclipses, the penumbral shadow does not appear until it is around 25–30% obscuration. It becomes slightly darker when the Earth blocks the sunlight until it reaches totality in some eclipses. In some eclipses, its penumbral shadow covers the whole surface, whereas the center of the Earth's shadow misses a portion of the Moon while every part of the Nearside sees a partial eclipse. These eclipses are very rare.

Glass bricks used in a wall Sidewalk skylight (also named 'pavement light') outside Burlington House, London Glass block, also known as glass brick, is an architectural element made from glass used in areas where privacy or visual obscuration is desired while admitting light, such as underground parking garages, washrooms, and municipal swimming baths. Glass block was originally developed in the early 1900s to provide natural light in industrial factories.

It is a variable star, considered an Orion variable, with occasional fading and other variability caused by obscuration from the surrounding dust. The apparent magnitude varies irregularly between 10.2 and 10.7. The properties of the star are calculated based on its maximum brightness, assumed to be the least obscured. The secondary is a T Tauri star, detected by distinctive spectral lines that could not be produced by the hotter primary star.

The mirror may be understood as a quality of the mindstream that denotes perceiving experience as it is without obscuration formed by klesha, etc. The mirror may be engaged in the advanced Tantric sadhana of the Gyulu. As the mirror, so the mind. The mirror as the mind, following Yogacara, reflects quality and form, though is not directly altered and is 'beyond all attributes and form' (Sanskrit: nirguna).

More recent observations have demonstrated that the dust obscuration may have been previously overestimated, so the distances may have been underestimated. If these new distance measurements are correct, then the galaxies in the IC 342/Maffei Group appear to be moving at the rate expected from the expansion of the universe, and the scenario of a collision between the IC 342/Maffei Group and the Local Group would be implausible.

Under the Chun Doo- hwan regime, South Korea's media policy had changed. The regime had closed several radio and TV networks and DBS was forced to give most of its shares to the government. The Dong-A Ilbo gave up DBS in 1980. The event that made forced closure possible was Dong-A Ilbo's deliberate obscuration of the Japanese flag in a photograph of the first ever Korean Olympic Gold medalist.

Optical beam smoke detectors work on the principle of light obscuration, where the presence of smoke blocks some of the light from the beam, typically through either absorbance or light scattering. Once a certain percentage of the transmitted light has been blocked by the smoke, a fire is signalled. Optical beam smoke detectors are typically used to detect fires in large commercial and industrial buildings, as components in a larger fire alarm system.

The greatest eclipse was in the Atlantic off the shore of Antarctica at 63.2 S & 9.5 W at 3:22 UTC and occurred after sunrise. It showed up to 25% obscuration of the sun at the middle of the Antarctic Peninsula at the 110th meridian and around 30% in the area of the South Pole, at the northern shore by the 20th meridian, it was close to 50% obscured. The subsolar marking was in Brazil.

The reddening observed during the deep dimming events of Tabby's Star is consistent with cooling of its photosphere. It does not require obscuration by dust. Such cooling could be produced by a decreased efficiency of heat transport caused e.g. by decreased effectiveness of convection due to the star's strong differential rotation, or by changes in its modes of heat transport if it is located near the transition between radiative and convective heat transport.

Sidewalk skylight (also named 'pavement light') made of load-bearing glass bricks in Burlington House, London Glass brick, also known as glass block, is an architectural element made from glass. The appearance of glass blocks can vary in color, size, texture and form. Glass bricks provide visual obscuration while admitting light. The modern glass block was developed from pre-existing prism lighting principles in the early 1900s to provide natural light in manufacturing plants.

This produces a very effective obscuration per weight of material used. This screen can then be sustained as long as the generator is supplied with oil, and--especially if a number of generators are used--the screen can build up to a considerable size. One 50 gallon drum of fog oil can obscure of land in 15 minutes. A tank creating smoke Whilst producing very large amounts of smoke relatively cheaply, these generators have a number of disadvantages.

A very small part occurred on the location of the previous eclipse, many areas occurred on the opposite side. The greatest eclipse was off the shore of Antarctica at 69.9 S & 100 E at 15:26 UTC (9:26 PM local time) and occurred at sunset. The eclipse began at sunrise in the Pacific Ocean and finished at sunset off the coast of Africa. It showed up to 25% obscuration at the middle of the Antarctic Peninsula.

Most numerous of the 40×46mm grenades, smoke rounds can be launched further than normal smoke hand grenades can be thrown, and come in numerous colors. These grenades are used for both signaling and obscuration, and come in two main types, "canopy" and "ground marker." 40×46mm canopy smoke grenades come in 3 colors: yellow (M676), white (M680), and red (M682). These were developed to penetrate dense canopy foliage in order to mark or signal a position.

The apparent dimensions of Maffei 1 depend strongly on the wavelength of light because of the heavy obscuration by the Milky Way. In blue light it is 1–2′ across while in the near infrared its major axis reaches 23′—more than 3/4 of the Moon's diameter. At a distance of 3 Mpc this corresponds to approximately 23 kpc. The total visible absolute magnitude of Maffei 1, MV=−20.8, is comparable to that of the Milky Way.

The Rise of Skywalker depicts Kylo Ren having his helmet repaired following its destruction in The Last Jedi. Abrams compared the fractured mask to Kintsugi, a Japanese ceramic art of repairing broken pottery which accentuates the breakage. The fractures in Kylo's mask represent those of his character, as opposed to its obscuration in The Force Awakens. The final scene of The Last Jedi depicts servant children playing with a toy of Luke, with one boy using the Force to grab a broom.

At an altitude of , the cruising altitude of a typical airliner, the mathematical curvature of the horizon is about 0.056, the same curvature of the rim of circle with a radius of 10 m that is viewed from 56 cm directly above the center of the circle. However, the apparent curvature is less than that due to refraction of light by the atmosphere and the obscuration of the horizon by high cloud layers that reduce the altitude above the visual surface.

Totality was visible from Ebon Atoll in German New Guinea (now in Marshall Islands), British Western Pacific Territories (the part now belonging to Kiribati), Line Islands (now in Kiribati), Phoenix Islands (now in Kiribati) on January 4th (Saturday), and Costa Rica on January 3rd (Friday). The green line means eclipse begins or ends at sunrise or sunset. The magenta line means mid eclipse at sunrise or sunset, or northern or southern penumbra limits. The green point means eclipse obscuration of 50%.

This equates to the frequency with which the radar beam passes over a given area. Frequent revisits are very important to the radar's ability to achieve track continuity and contribute to an increased probability of target detection by lessening the chance of obscuration from screening by trees, buildings, or other objects. A fast revisit rate becomes critical to providing an uncorrupted track when a target moves in dense traffic or is temporarily obscured, if only by trees along a road.

Besides promoting a general inclusiveness and non- sectarian attitude towards all the different Buddhist lineages and schools, Kongtrül was known to promote a shentong view of emptiness as the highest view. His view of Prasangika Madhyamaka is outlined in the following verse from the Treasury of Knowledge: > Conceptual imputations are abandoned; all things are merely designations. > Compounded phenomena are deceptive; nirvana is not deceptive. > The root of samsara is clinging to true existence, which generates the > obscuration of the afflictive emotions.

The arms were previously missed due to M82's high disk surface brightness, the nearly edge-on view of this galaxy (~80°), and obscuration by a complex network of dusty filaments in its optical images. These arms emanate from the ends of the NIR bar and can be followed for the length of 3 disc scales. Assuming that the northern part of M82 is nearer to us, as most of the literature does, the observed sense of rotation implies trailing arms.

Solar activity and related events have been regularly recorded since the time of the Babylonians. In the 8th century BC, they described solar eclipses and possibly predicted them from numerological rules. The earliest extant report of sunspots dates back to the Chinese Book of Changes, . The phrases used in the book translate to "A dou is seen in the Sun" and "A mei is seen in the Sun", where dou and mei would be darkening or obscuration (based on the context).

The beginning and the end of the play is effected through Sudarshana, who in the Ahirbudhanya Samhita is the will of the omnipotent, omniscient, omnipresent God. The Sudarshana manifests in 5 main ways to wit the 5 Shaktis, which are creation, preservation, destruction, obstruction, and obscuration; to free the soul from taints and fetters which produce vasanas causing new births; so as to make the soul return to her natural form and condition which she shares with the supreme lord, namely, omnipotence, omniscience, omnipresence.

There are several methods used for detecting and measuring particle size or size distribution — light blocking (obscuration), light scattering, Coulter principle and direct imaging. The light blocking optical particle counter method is typically useful for detecting and sizing particles greater than 1 micrometre in size and is based upon the amount of light a particle blocks when passing through the detection area of the particle counter. This type of technique allows high resolution and reliable measurement. The light scattering method is capable of detecting smaller-sized particles.

It is during the "acmatic" phases, when the national passionarity reaches its maximum heat, that the great conquests are made. Gumilyov described the current state of Europe as deep inertia, or "introduction to obscuration", to use his own words. The passionarity of the Arabic world, on the other hand, is still high, according to him. Drawing inspiration from the works of Konstantin Leontyev and Nikolay Danilevsky, Gumilyov regarded Russians as a "super-ethnos" which is kindred to Turkic-Mongol peoples of the Eurasian steppe.

The eclipse was visible in Northern and Southern Antarctica including the South Pole, a tiny portion near the Antarctic Peninsula, a tiny part of the Atlantic and the Indian Ocean. It was during the decade that Antarctica was being explored by Europeans and added to the known atlas of the time. The eclipse started at sunrise in the Indian Ocean at around the 50th meridian east, it finished at sunset not far from the Antarctic Peninsula. It showed about up to 20-25% obscuration in Antarctica.

Harmattan Haze in Abuja. Haze over the Mojave Desert from a brush fire in Santa Barbara, California, seen as the Sun descends on the 2016 June solstice, allows the Sun to be photographed without a filter.Haze is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates obscure the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand, and snow.

Despite being opaque at visible-light wavelengths, use of the Very Large Telescope at Cerro Paranal has revealed the presence of about 3,700 blocked background Milky Way stars, some 1,000 of which are visible at infrared wavelengths. Careful measurements of the degree of obscuration resulted in a finely sampled and accurate mapping of the dust distribution inside the cloud. Observations obtained with Herschel Space Observatory were able to constrain the distribution of the dust component and its temperature even more. Having a dark cloud in the solar neighborhood greatly facilitates observation and measurement.

It showed up to 30% obscuration in the area of Cape Town and Cape Agulhas up to 99% inside the maximum width of band. The greatest eclipse was in the middle of Antarctica east of the Prime Meridian at 75.4 S, 15.1 E at 8:09 UTC (9:09 AM local time) and lasted for 22 seconds, the maximum width of band was only 42 km (26 miles), the view around it was partly dark even inside the clouds. The subsolar marking was east of Madagascar and close to the Mascarene Islands.

Conditions of glare, partial obscuration, rain, snow, fog, and darkness all compound the problem. Even when a human is directed to look at the actual location on a monitor of a subject in these conditions, the subject will usually not be detected. The A.I. is able to impartially look at the entire image and all cameras' images simultaneously. Using statistical models of degrees of deviation from its learned pattern of what constitutes the human form it will detect an intruder with high reliability and a low false alert rate even in adverse conditions.

Nature, "Dust-free quasars in the early Universe", Linhua Jiang, Xiaohui Fan, W. N. Brandt, Chris L. Carilli, Eiichi Egami1, Dean C. Hines, Jaron D. Kurk, Gordon T. Richards, Yue Shen, Michael A. Strauss, Marianne Vestergaard, Fabian Walter, 18 March 2010, vol.464, pp.380–383, , , (accessed 6 April 2010) QSO J0005-0006 was found to be dust free in a 2006 study of distant quasars, and confirmed as such in the 2010 study. The 2010 study removed the potential of masking the dust emission signature occurring, by studying the amount of obscuration of the quasar.

The eclipse started at sunrise near Valparaiso and Santiago, Chile and ended at sunset in the Indian Ocean offshore from Antarctica around the third of the way to Western Australia. It showed up to 25-30% obscuration of the sun at South America's southern tip, 30% within the South Pole and 50% at the west of the middle portion of the Peninsula. The center of the Moon's shadow was missed by about 1,300 km above the area (67.6 S) south of the Antarctic Circle. The subsolar marking was west of Namaqualand (then also South West Africa, now Namibia).

It is an important laboratory for studying stellar evolution, since the cluster is well populated, has negligible amounts of dust obscuration, and all its stars are at the same distance and age, except for approximately 30 anomalous blue stragglers. These blue stragglers are generally the results of mass transfer in binaries or stellar collisions. This artist's impression video shows a hot Jupiter exoplanet orbiting close to a star in Messier 67. M67 is one of the most-studied open clusters, yet estimates of its physical parameters such as age, mass, and number of stars of a given type, vary substantially.

The assaulting troops were landed at the wrong place due to obscuration of key features ashore as a result of the pre-landing bombardment, and a failure to clear all of the beach obstacles. As a result two of the three assault battalions landed too far left, and troops from each battalion became mixed up with others, causing some confusion. Despite this, the landing was opposed only by a small volume of fire, and within 15 to 20 minutes the assault troops had established a beachhead. The landing force suffered no casualties during this first part of the operation.

NGC 3147 has been characterised as a Seyfert II galaxy. It is considered the best candidate to be a true type II Seyfert galaxy, galaxies which feature optical/UV spectrum lacking broad emission lines due to the lack of the broad line region rather than its obscuration, since the nucleus is simultaneously seen unobscured in the X-rays. The galaxy was observed stimultaneously in the optical and X-ray spectrum by Bianchi et al. and concluded that the X-ray spectrum is unabsorbed while its optical spectrum lacks broad lines, a mismatch with respect to the Unification Model.

The two major techniques of squad assault are bounded fire and advancing under the cover of suppressive fire of supporting units. Bounded fire entails having one element of the squad provide covering fire and field obscuration while the second element maneuvers forward to provide covering fire that allows the first element to leapfrog forward. This process is repeated until the maneuver element is in grenade range of the enemy positions. Advancing under the cover of supporting units requires the squad to stealthily advance towards the enemy position from a weakly held sector after the enemy has been suppressed by overwhelming fire.

In the Orion Nebula the proplyds observed are usually one of two types. Some proplyds glow around luminous stars, in cases where the disk is found close to the star, glowing from the star's luminosity. Other proplyds are found at a greater distance from the host star and instead show up as dark silhouettes due to the self-obscuration of cooler dust and gases from the disk itself. Some proplyds show signs of movement from solar irradiance shock waves pushing the proplyds. The Orion Nebula is approximately 1,500 light-years from the Sun with very active star formation.

A Hubble Space Telescope combined image of eight quasar ionisation echoes, or Voorwerpjes. CREDITS: NASA, ESA and Prof. William Keel In February 2012, W. C. Keel and others published a paper in the Monthly Notices of the Royal Astronomical Society. As a result of the interest in similar ionized clouds for the study of both the history and obscuration of Active Galactic Nucleus (AGN), participants in the Galaxy Zoo (GZ) project carried out a wide search for such clouds using data from the Sloan Digital Sky Survey (SDSS). This search yielded a list of 19 galaxies with AGN-photoionized clouds detected to beyond 10 kiloparsecs from the nuclei.

Together with his student Ido Finkelman, and with colleagues from Russia and the Netherlands, they showed that the visible ring is part of an even larger ring of neutral hydrogen and proposed that the ring represents material accreted by the elliptical core at least one billion years ago. Hoag's Object would, therefore, represent a much undisturbed galaxy . Brosch and colleagues, and other students, investigated the properties of extragalactic dust by concentrating on elliptical galaxies with dark lanes. Modeling the light distribution of the unaffected parts of a galaxy, and subtracting from it the detected light distribution, they derived the amount of light missing because of the dust obscuration.

In an asymmetrical Cassegrain, the mirror(s) may be tilted to avoid obscuration of the primary or to avoid the need for a hole in the primary mirror (or both). The classic Cassegrain configuration uses a parabolic reflector as the primary while the secondary mirror is hyperbolic. Modern variants may have a hyperbolic primary for increased performance (for example, the Ritchey–Chrétien design); and either or both mirrors may be spherical or elliptical for ease of manufacturing. The Cassegrain reflector is named after a published reflecting telescope design that appeared in the April 25, 1672 Journal des sçavans which has been attributed to Laurent Cassegrain.

Among human phenotypes, blue-green-gray eyes are a relatively rare eye color and the exact color is often perceived to vary according to its surroundings. The iris is usually strongly pigmented, with the color typically ranging between brown, hazel, green, gray, and blue. Occasionally, the color of the iris is due to a lack of pigmentation, as in the pinkish-white of oculo-cutaneous albinism, or to obscuration of its pigment by blood vessels, as in the red of an abnormally vascularised iris. Despite the wide range of colors, the only pigment that contributes substantially to normal human iris color is the dark pigment melanin.

Keratoendotheliitis fugax hereditaria is an autosomal dominantly inherited disease of the cornea, caused by a point mutation in cryopyrin (also known as NALP3) that in humans is encoded by the NLRP3 gene located on the long arm of chromosome 1. In keratoendotheliitis fugax hereditaria, patients suffer from periodical transient inflammation of the corneal endothelium and stroma, leading to short term obscuration of vision and, in some patients after repeated attacks, to central corneal stromal opacities. Approximately 50 known cases have been reported in the literature. The disease so far has only been described from Finland, but exome databases suggest it may be more widely distributed in people of European ancestry.

The low density of small craters in the oldest class, c1, results from their destruction by impacts and obscuration by ejecta and volcanic material over a long period of mercurian history. The intercrater plains and younger plains materials probably have mixed origins, and they consist of both volcanic and impact ejecta-related deposits. The plains materials accumulated mostly in low-lying areas and have buried or partly buried older craters and surfaces. Their relative ages and thicknesses are reflected by the number of craters visible on their surfaces: where crater densities are high, the plains material is relatively old or thin; low crater densities indicate relatively thick, young deposits.

The eclipse was visible in Western Antarctica along with the easternmost portions including the sea in the west, the South Pole and a part of the Trans-Antarctic Mountains, it was also visible in a part of the southernmost of the Pacific. The eclipse edges nearly touch the southernmost of the Atlantic. The eclipse started at sunrise in the Pacific at around the 45th parallel and east of the 180th meridian, it finished at sunset about 40% of the way between the South Pole and the Atlantic-Indian Ocean boundary. It showed about up to 20-25% obscuration in Antarctica and over 25% west of the 180th meridian in Antarctica.

Several hypotheses have been proposed to explain the star's large irregular changes in brightness as measured by its light curve, but none to date fully explain all aspects of the curve. One explanation is that an "uneven ring of dust" orbits Tabby's Star. In another explanation, the star's luminosity is modulated by changes in the efficiency of heat transport to its photosphere, so no external obscuration is required. A third hypothesis, based on a lack of observed infrared light, posits a swarm of cold, dusty comet fragments in a highly eccentric orbit, however, the notion that disturbed comets from such a cloud could exist in high enough numbers to obscure 22% of the star's observed luminosity has been doubted.

Tests One and Two were fully instrumented with a high sensor density, including measurements of temperature, incident heat, gas velocities, smoke obscuration, wall temperature and structure deflection, among others. The tests varied in that Test One allowed the fire to develop freely to post-flashover conditions, while Test Two incorporated sensor-informed ventilation management and was extinguished before post-flashover conditions were attained. Both tests had approximately 300 sensors monitoring several different characteristics of the fire environment, but Test One had about 160 additional sensors monitoring the structural response. These experiments endeavoured to establish a highly monitored fire in a realistic residential scenario, allowing for several different modern fire safety engineering tools to be tested.

Forecasting the tracks of tropical cyclones since 1990 has improved by approximately 50%; however, in the same time period there has not been a corresponding improvement in forecasting the intensity of these storms. A better understanding of the inner core of tropical storms could lead to better forecasts; however, current sensors are unable to gather a sufficient quality of data on the inner core due to obscuration from rain bands surrounding it and to infrequent sampling. In order to improve the models used in intensity forecasts, better data are required."CYGNSS." University of Michigan. Retrieved: August 15, 2015 CYGNSS will measure the ocean surface wind field using a bi-static scatterometry technique based on GPS signals.

Light pollution map of EuropeThe visibility of celestial objects in the night sky is affected by light pollution, with the presence of the Moon in the night sky historically hindering astronomical observation by increasing the amount of ambient lighting. With the advent of artificial light sources, however, light pollution has been a growing problem for viewing the night sky. Special filters and modifications to light fixtures can help to alleviate this problem, but for the best views, both professional and amateur optical astronomers seek viewing sites located far from major urban areas. In order to avoid light pollution of Earth's sky, among other reasons, many telescopes are put outside of the Earth's atmosphere, where not only light pollution, but also atmospheric distortion and obscuration are minimized.

Sankara, in his commentary on Chapter XIII of the Bhagavad Gita with regard to the distinction between Ishvara and Jiva since the identification of the prajna (the self in deep sleep-state) with Ishvara is problematic, states:- “Now as to the objections that Ishvara would be a samsarin if He be one with Kshetrajna, and that if Kshetrajnas be one with Ishvara there can be no samsara because there is no samsarin: these objections have been met by saying that knowledge and ignorance are distinct in kind and effects, - that all that is knowable is the Kshetra, and Kshetrajna is the knower and none else.” And, therefore, avarna dosha (obscuration of intellect) which is the basic feature of deep sleep affects only individual beings and not God.

The aircraft was destroyed, killing 87 of its 89 occupants. One of the two survivors died after two hours, and the other, Leopold Chouinard, died of burn injuries on December 11, 1973; Chouinard is not listed by the National Transportation Safety Board (NTSB) as an official Delta 723 fatality due to requirements in the Code of Federal Regulations which, in 1973, defined a crash fatality as taking place within 7 days of an accident; the rule was subsequently changed in 2018, such that death must occur within 30 days of a crash. The weather conditions at the time of the crash were partial obscuration and fog, with a ceiling of , 1/2 mile visibility and light winds. Runway visual range (RVR) was .

The eclipse was visible in much of the three southern oceans including the southeast part of the Pacific, most of the South Atlantic Ocean and its islands and small parts of the Indian Ocean surrounding Antarctica with a tiny bit probably excluded. It also included the southern tip of South America which included Patagonia and the Falkland Islands and the Cape Colony (now Southern and Northern Cape which are part of South Africa). It showed 30% obscuration at Ushuaia and the Falklands (or Malvinas), 50% around the South Georgia, South Orkney and Livingston Islands, 60% at the north of the Antarctic Peninsula and 80% in the middle part. The rim of the eclipse included southeast of Tuamotu Islands, Puerto Montt and areas south of Buenos Aires.

Direct imaging with the Hubble Space Telescope shows extensive dust clouds out to a radius of around 2000 astronomical units from R Coronae Borealis, corresponding to a stream of fine dust (composed of grains about 5 nm in diameter) associated with the star's stellar wind, and coarser dust (composed of grains with a diameter of around 0.14 µm) ejected periodically. The obscuration appears to happen closer to the star as clouds of carbon condense at shock regions in an expanding front. "Puffs" of dust emitted from the star condense at about from the surface, and are visible as cometary knots when they lie to side of the star. There is also a shell about 4 pc wide containing dust at 25 K, which may be a fossil planetary nebula.

Active galactic nuclei are the most luminous persistent sources of electromagnetic radiation in the universe, and as such can be used as a means of discovering distant objects; their evolution as a function of cosmic time also puts constraints on models of the cosmos. The observed characteristics of an AGN depend on several properties such as the mass of the central black hole, the rate of gas accretion onto the black hole, the orientation of the accretion disk, the degree of obscuration of the nucleus by dust, and presence or absence of jets. Numerous subclasses of AGN have been defined based on their observed characteristics; the most powerful AGN are classified as quasars. A blazar is an AGN with a jet pointed toward the Earth, in which radiation from the jet is enhanced by relativistic beaming.

Simulaser was acquired by Applied Solar Energy Corp. (ASEC, City of Industry, CA), its major supplier of silicon detectors, in 1984.Lasers & Applications, January 1985 Later, under contract from Fairchild-Weston Systems, Simulaser produced the laser and detector systems for the AGES/ADII (Air-to-Ground Engagement System/Air Defense II) program for the US Army, outfitting a number of helicopters with training systems and producing laser simulators for the HGSS/GVLLD (Hellfire Ground Support System Simulator/Ground-based Vehicle Laser Locator Designator). Simulaser's HGSS/GVLLD Simlator Simulaser's MITS unit Simulaser also produced the early low rate of production run of MITS (Multiple Independent Target System) and in 1989 won a development contract from the US Army for STOM (Shoot-through Obscuration Miles) that utilized long-wavelength lasers instead of semiconductor lasers in order to penetrate battlefield obscurants.

The eclipse was visible in the islands of Java, Bali, Sunda (the three compromising a part of Indonesia today) and Timor including Portuguese Timor (now East Timor), the Asian islands, almost the whole of Australia with the exception of the Cape York Peninsula, Lord Howe Island, Norfolk Island, Macquarrie Islands, New Zealand, Chatham Islands, Antipodes and some remaining small islands. In Australia, it showed up to 10% obscuration in the south of the Gulf of Carpentaria, around 15% in Brisbane, 25–30% in Central Australia, around 40% in Sydney, 50% in Melbourne, around 55% in Tasmania and the Nullarbor Plain and around 60% in Perth, Western Australia. Elsewhere it showed 10% in the north tip of New Zealand's North Island, up to 30% in the area of Wellington, 45% in Otago. and 60% in the Chatham Islands.

Today's observatory was initiated by the Advanced Research Projects Agency (ARPA) in 1961 as the ARPA Midcourse Optical Station (AMOS). It was first proposed by R. Zirkind of ARPA's staff for imaging ballistic missile payloads and decoys during their midcourse phase, and other space objects including satellites, in the infrared spectrum, as well as for performing astronomical research. Its location on Mount Haleakala was nearly ideal for its altitude high above much obscuration by water vapor, for its midcourse location between the missile launch site at Vandenberg Air Force Base and its main reentry location at Kwajalein Atoll, and for its low-latitude location which was advantageous for observing satellites. The AMOS effort formally began with an amendment to an existing ARPA order with the University of Michigan's Institute for Science and Technology, which was to design, construct, and operate the facility.

Historically, work on radio-loud unification has concentrated on high-luminosity radio-loud quasars. These can be unified with narrow-line radio galaxies in a manner directly analogous to the Seyfert 1/2 unification (but without the complication of much in the way of a reflection component: narrow-line radio galaxies show no nuclear optical continuum or reflected X-ray component, although they do occasionally show polarized broad-line emission). The large-scale radio structures of these objects provide compelling evidence that the orientation-based unified models really are true. X-ray evidence, where available, supports the unified picture: radio galaxies show evidence of obscuration from a torus, while quasars do not, although care must be taken since radio-loud objects also have a soft unabsorbed jet-related component, and high resolution is necessary to separate out thermal emission from the sources' large-scale hot-gas environment.

The redshifts of quasars are of cosmological origin. The term originated as a contraction of quasi-stellar [star-like] radio source because quasars were first identified during the 1950s as sources of radio-wave emission of unknown physical origin, and when identified in photographic images at visible wavelengths they resembled faint, star-like points of light. High-resolution images of quasars, particularly from the Hubble Space Telescope, have demonstrated that quasars occur in the centers of galaxies, and that some host galaxies are strongly interacting or merging galaxies. As with other categories of AGN, the observed properties of a quasar depend on many factors, including the mass of the black hole, the rate of gas accretion, the orientation of the accretion disk relative to the observer, the presence or absence of a jet, and the degree of obscuration by gas and dust within the host galaxy.

The eclipse was visible in the northeast of Brazil, most of Africa and Europe. The umbral portion included Portuguese Cape Verde (now independent) with the island of Santo Antão, the Arguin region (now part of Mauritania), the Moorish lands, the Regency of Algiers (then under Ottoman suzerainty, now Algeria), Sardinia, Italy with southern Tuscany, Umbria and modern Emilia-Romagna, Slovenia (then called Carniola), parts of the Venetian Republic, some of the lands were ruled by Napoleon I, the Habsburg lands of Austria, Hungary (one part including modern day Slovakia), Moravia (now part of the Czech Republic), contemporary Poland and the west of the Russian Empire between Moscow and Saint Petersburg. The eclipse was 50% obscuration near a part of Brazil at Ceará, the Kingdom of Benin, el Alamein, the Caucasus and off the west shores of Iceland. Areas that were in the edge of the eclipse included Bahía, Cabinda (sometimes as Kabinda), the lower Congo, Bahrain, the Qatar Peninsula and Shiraz.

Starting in the 1960s, Pahor's work started to become quite well known in Yugoslavia, but it did not gain wide recognition due to opposition from the Slovenian Communist Regime, which saw Pahor as a potential subversive figure. Nevertheless, he became one of the major moral referents for the new postwar generation of Slovene writers, including Drago Jančar, who has frequently pointed out his indebtedness to Pahor, especially in the essay The Man Who Said No, published in 1993 as one of the first comprehensive assessments of Pahor's literary and moral role in the postwar era in Slovenia. Pahor's major works include Vila ob jezeru (A Villa by the Lake), Mesto v zalivu (The City in the Bay), Nekropola (Pilgrim among the Shadows), a trilogy about Trieste and the Slovene minority in Italy (1920-1947) Spopad s pomladjo (A Difficult Spring), Zatemnitev (Obscuration), V labirintu (In the Labyrinth), and Zibelka sveta (The Cradle of the World). Five of his books have been translated into German.

An even more luminous yet closer star, WR 25, appears to be most likely to the title. Another nearer star, Eta Carinae, which was the second-brightest star in the sky for a few years in the 19th century, appears to be slightly more luminous than WR 102ka, but is known to be a binary star system. There is also the more recently discovered Pistol Star that, like the Peony star, derives its name from the shape of the nebula in which it is embedded, and which it has probably created through heavy mass loss via fierce stellar winds and perhaps also major "mini-supernova-like" eruptions as happened to Eta Carinae around the 1830s-1840s creating the lobes observed by the Hubble Space Telescope. The luminosities of the Pistol Star, Eta Carinae, and WR 102ka are all rendered somewhat uncertain due to heavy obscuration by galactic dust in the foreground, the effects of which must be corrected for before their apparent brightness can be reduced to estimate their total radiated power or bolometric luminosity.

Within the Madhyamaka school of Mahayana Buddhism, Candrakirti identifies the self as: Buddhapālita adds, while commenting on Nagārjuna's Mūlamadhyamakakārikā, For the Madhyamaka Buddhists, 'Emptiness' (also known as Anatta or Anatman) is the strong assertion that all phenomena are empty of any essence, and that anti-essentialism lies at the root of Buddhist praxis and it is the innate belief in essence that is considered to be an afflictive obscuration which serves as the root of all suffering. However, the Madhyamaka also rejects the tenets of Idealism, Materialism or Nihilism; instead, the ideas of truth or existence, along with any assertions that depend upon them are limited to their function within the contexts and conventions that assert them, possibly somewhat akin to Relativism or Pragmatism. For the Madhyamaka, replacement paradoxes such as Ship of Theseus are answered by stating that the Ship of Theseus remains so (within the conventions that assert it) until it ceases to function as the Ship of Theseus. In Nagarjuna's Mulamadhyamakakarika Chapter XV examines essence itself.

The "outer" face of each penalty timer had a single hand that avoided obscuration of the "inner" face and its own, "solid" single hand, through the use of metal rods forming the outer hand's "shaft", holding its hand's "pointer" headCloseup of Chicago Stadium's Bulova Sports Timer showing close-up details — the set of two concentric faces for each penalty timer dial could handle two penalties for each set, with an illuminated "2" on each penalty timer dial lighting up to display a minor penalty infraction. It was difficult to read how much time was left in a period of play on the main game timer's large face, as each minute of play was marked by a longer line on every third "seconds" increment on the central main dial, due to the minute hand's twenty-minute "full rotation" timing capacity for one period of ice hockey. The difficulty was compounded on the main central dial from the aforementioned minute and sweep-second hands being in constant motion during gameplay. The "Sports Timer's" only digital displays were for scoring and for penalized players' numbers, each digit comprising a six-high, four-wide incandescent light dot matrix display.
