These fade-outs were found to not just be caused by solar flares, but also by active solar prominence regions, bright surges, and subflares at the edge (or limb) of the Sun.

This video shows the particle flow around Earth as solar ejecta associated with a coronal mass ejection strike. A coronal mass ejection (CME) is a significant release of plasma and accompanying magnetic field from the solar corona. They often follow solar flares and are normally present during a solar prominence eruption. The plasma is released into the solar wind, and can be observed in coronagraph imagery.

After living for generations as persecuted refugees, the Letarri people set their sights on a far-off planet as a promising new home. But when the interstellar mission to colonize the new world goes terribly awry, the fate of their people falls into the hands of a lone adventurer. It's up to the player to unravel the mystery of what happened. The game's title refers to the natural phenomenon of a solar prominence.

A solar prominence, with images of Jupiter and Earth for size comparison. A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the solar corona. While the corona consists of extremely hot ionized gases, known as plasma, which do not emit much visible light, prominences contain much cooler plasma, similar in composition to that of the chromosphere.

The first observation of a transiting extrasolar planet in Slovakia was performed at the observatory. The solar physics researchers perform solar prominence and chromosphere features observations in the H-alpha line. The observatory is also a member of the European bolide network and it has been developing its own TV meteor detection grid. Besides photographic all-sky cameras, fish-eye all-sky semi-automated meteor detection devices are located at Modra observatory, near Tesárske Mlyňany and in Kysucké Nové Mesto.

Solar prominence video clip A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in the shape of a loop. Prominences are anchored to the Sun's surface in the photosphere and extend outwards into the corona. While the corona consists of high temperature plasma, which does not emit much visible light, prominences contain much cooler plasma, similar in composition to that of the chromosphere. Prominence plasma is typically a hundred times cooler and denser than coronal plasma.

In space, solarnauts Harris, Asher and Camp fire a smaller probe through a solar prominence and succeed in capturing fragments of matter. However, by the time the probe returns to the main spacecraft, the increasing solar radiation has caused Sun Probes retro-rockets to fail, locking it on a collision course with the Sun. On TV, Benson implores International Rescue to save the crew. Alan and Scott (voiced by Matt Zimmerman and Shane Rimmer) suggest remote-firing Sun Probes rockets by radio beam from Thunderbird 3.

Solar activity and related events have been recorded since the 8th century BCE. Babylonians inscribed and possibly predicted solar eclipses, while the earliest extant report of sunspots dates back to the Chinese Book of Changes, . The first extant description of the solar corona was in 968, while the earliest sunspot drawing was in 1128 and a solar prominence was described in 1185 in the Russian Chronicle of Novgorod. The invention of the telescope allowed major advances in understanding, allowing the first detailed observations in the 1600s.

The Great Eruptive Solar Prominence of June 4, 1946 Dr. Bernard Lyot developed the first coronagraph to study the Sun's corona. Improved coronagraphs are used at the High Altitude Observatory by Dr. Walter Roberts and at the Evans Solar Facility by Dr. J. W. Evans. Dr. Donald H. Menzel was the first to use the coronagraph in America. These coronagraphs are used to film structures on the Sun called prominences and spicules which show matter flowing on the surface in structures many times the size of the Earth.

A picture recording a Hyder flare which occurred over a three-hour span, on November 1, 2014. A Hyder flare is slow, large-scale brightening that occurs in the solar chromosphere.Space Weather Services: Hyder Flares at the Australian Government Bureau of Meteorology; retrieved February 6, 2016 It resembles a large but feeble solar flare and is identifiable as the signature of the sudden disappearance of a solar prominence (a "disparition brusque"). These events occur in the quiet Sun, away from the active regions or sunspot groups, and typically in the polar crown filament zone.

TRACE image of a coronal arcade Wave and oscillatory phenomena are observed in the hot plasma of the corona mainly in EUV, optical and microwave bands with a number of spaceborne and ground-based instruments, e.g. the Solar and Heliospheric Observatory (SOHO), the Transition Region and Coronal Explorer (TRACE), the Nobeyama Radioheliograph (NoRH, see the Nobeyama radio observatory). Phenomenologically, researchers distinguish between compressible waves in polar plumes and in legs of large coronal loops, flare-generated transverse oscillations of loops, acoustic oscillations of loops, propagating kink waves in loops and in structures above arcades (an arcade being a close collection of loops in a cylindrical structure, see image to right), sausage oscillations of flaring loops, and oscillations of prominences and fibrils (see solar prominence), and this list is continuously updated. Coronal seismology is one of the aims of the Atmospheric Imaging Assembly (AIA) instrument on the Solar Dynamics Observatory (SDO) mission.
