That which is prominent; a protuberance.
See solar flare.
Large cloud of plasma extending above the Sun's chromosphere. They are divided into two main classes. Quiescent types show little motion, may last for several solar rotations and disappear slowly. Eruptive or active types form and disappear very quickly, and may grow to tremendous size.
A mass of cloud-like gas that rises from the Sun's chromosphere
Solar gas protruding over the limb, visible to the naked eye only at eclipses but also observed outside of eclipses by its emission line spectrum. Prominences are at approximately the same temperature as the chromosphere.
a condensation of cool material in the corona.
Cloud of gas elevated above the solar surface.
Loop or sheet of glowing gas ejected from an active region on the solar surface, which then moves through the inner parts of the corona under the influence of the Sun's magnetic field.
something that bulges out or is protuberant or projects from a form
a dense cloud of incandescent ionized solar gas projecting above the sun's chromosphere into the corona and held in place by the sun's magnetic field
a magnetic field loop that carries solar material with it in a arch or loop high above the disk and back down
an arc of gas suspended by magnetic fields
A term identifying cloud-like features in the solar atmosphere. The features appear as bright structures in the corona above the solar limb and as dark filaments when seen projected against the solar disk.
A cloud of cooler plasma extending high above the Sun"s visible surface, rising above the photosphere into the corona.
A cloud, or plume, of hot, luminous gas in the Sun's corona. It appears bright when seen against the cool blackness of space. When they are in silhouette against the disc they are known as filaments. They are mainly composed of hydrogen, helium and calcium
An explosion of hot gas that erupts from the Sun's surface. Solar prominences are usually associated with sunspot activity and can cause interference with communications on Earth due to their electromagnetic effects on the atmosphere.
a strand of relatively cool gas in the solar corona which appears bright when seen at the edge of the Sun against the blackness of space. Ptolemy 87-150 Alexandrian astronomer, mathematician, and geographer who based his astronomy on the belief that all heavenly bodies revolve around the Earth.
an eruption of hot gas at the surface of the Sun.
A phenomenon in the solar corona that commonly appears like a flame above the limb of the Sun.
Eruptions of clouds of solar material that extend into the outer chromosphere and inner corona . They can appear as loops (when they follow the sun’s magnetic field ) or as sprays (when ejected by the sun’s magnetic field ). (TOP OF THE PAGE) (CLOSE WINDOW)
A plasma protuberance above the surface of the Sun, originating in the chromosphere and extending sometimes to a height of several hundred thousand kilometers.
A structure in the corona consisting of cool plasma supported by magnetic fields. Prominences are bright structures when seen over the solar limb, but appear dark when seen against the bright solar disk. Prominences seen on the disk are also known as filaments. more
Complex structures of relatively cool, dense solar material that extend into the outer chromosphere and inner corona. They are generally static and believed to be supported by magnetic forces. They can appear as loops on the edge of the solar disk or limb. Their shape is probably controlled by the Sun's magnetic field. Sometimes they erupt, often in association with coronal mass ejections.
A loop or sheet of glowing gas ejected from an active region on the surface of the sun. Like sunspots, this is associated with the sun's magnetic field and is highly variable. This phenomenon can be observed through an H-alpha filter with the solar telescope.
A large-scale gaseous formation above the surface of the Sun.
An eruption of hot gases above the photosphere of the Sun. Prominences are most easily visible close to the limb of the Sun, but some are also visible as bright streamers on the photosphere.
A filament-like protuberance from the chromosphere of the sun. Prominences can be observed visually (optically) whenever the sun's disk is masked, as during an eclipse or by using a coronagraph; and can be observed instrumentally by filtering in certain wavelengths, as with a spectroheliograph. A typical prominence is 6000 to 12 000 km thick, 60 000 km high, and 200 000 km long. These features appear as filaments when they are seen against the solar disk.
