You can see the prominence form, rise up, and then erupt away into space over the course of one day, on October 6-7, 2012. Sometimes this material rains back down to the surface, and sometimes it escapes entirely.

A prominence is a large bright feature extending outward from the Sun's surface, often in a loop configuration. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.

A prominence is made up of relatively cold, dense plasma supported by the local magnetic field from falling back into the sun. They can survive like this for 200 days. The temperature of the plasma in a prominence is about 5000 K.

A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space.

Prominences are dense clouds of material suspended above the surface of the Sun by loops of magnetic field.

Prominence is a structure in the Sun's 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.

prominence 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.

prominence: 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.

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.

Prominence A cloud of cooler plasma extending high above the Sun"s visible surface, rising above the photosphere into the corona.

A region of cool (104 K), high-density gas embedded in the hot (106 K), low-density Solar corona. Prominences are the flamelike tongues of gas that appear above the limb of the Sun.

An eruption of gas from the chromosphere of a star. Solar prominences are visible as part of the corona during a total solar eclipse.

Cloud of gas elevated above the solar surface.
Proper motion:
The apparent drift of a star across the sky, compounded from the motion of the star and the sun.

prominence - (n.)
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.

Sun Prominence
This image was acquired from NASA's Skylab space station on December 19, 1973. It shows one of the most spectacular solar flares ever recorded, propelled by magnetic forces, lifting off from the Sun.

Finally, solar prominences rise up through the chromosphere from the photosphere, sometimes reaching altitudes of 150,000 kilometers. These gigantic plumes of gas are the most spectacular of solar phenomena, aside from the less frequent solar flares.

prominence A filamentlike protuberance from the chromosphere of the sun. See flocculi. Compare flare.

Vast star systems containing thousands of billions of stars, dust and gas, held together by gravity.

" So great is its prominence that it has two "announcer stars" that from the mid- northern hemisphere rise before it, Procyon and Mirzam.

The Yerkes (or Morgan) scheme uses strictly the relative prominence of disk and bulge (the Hubble classification includes arm structure) - these are generally correlated, but not uniquely.

(A magnetic polarity flip between northern and southern sunspots means one complete cycle is actually 22 years.) Part of this activity is the enhanced prominence of sunspots: dark cool regions on the Sun that are a mere 3,000 C, ...

Solar flares are eruptions more powerful than surge prominences (a flare is shown in the Sun + planets montage above). They will last only a few minutes to a few hours. A lot of ionized material is ejected in a flare.

He initiated in 1866 the spectroscopic observation of sunspots, and in 1868 he found that solar prominences are upheavals in a layer around the Sun, which he named the chromosphere.

For example, SOHO is a satellite that is run jointly by ESA and NASA, and it does take images of giant flares and prominences, which are like giant explosions on the sun.

The Sun's faint corona will be visible, and even the chromosphere, solar prominences, and possibly even a solar flare may be visible.

I'm talking about the solar flares/prominences. You could see them using telescope with an Hα filter.

Prominences that seem to float above the photosphere are supported by, and threaded through with, magnetic fields. All the streamers and loops seen in the corona (the Sun's extended upper atmosphere) are shaped by magnetic fields.

Southern Cross
A small but very distinctive . The Southern Cross inspired many ancient cultures because of it prominence in the night sky. The VLT third Unit Telescope is named after the Southern Cross in the Mapuche language, "Melipal".

active sun
The condition of the Sun characterized by unusually large numbers and size of spots, flares, and prominences. It is especially associated with maxima of the solar cycle.

Two months later, Norman Lockyer used a cleaver technique and managed to observe the Solar prominence without waiting for an eclipse.

At this point the sky is sufficiently dark that planets and brighter stars are visible, and if the Sun is active one can typically see solar prominences and flares around the limb of the Moon, even without a telescope (see image at left).

Examples include prominences, which are great arcs of gas that extend outwards from the Sun, and solar flares which are great explosions and jets of gas from the solar surface.
