SOLAR PROMINENCES
Gases trapped at the edge of the Sun which appear to shoot outward from the Sun's surface.
SOLAR SYSTEM
The Sun and all of the planets, comets, etc. which revolve around it.
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.
View some solar prominences and flares. Hydrogen-alpha filters are commercially available for small telescopes. They are quite expensive, but many science departments will have one.
The spectroheliograph, originally designed for photographing the solar prominences, disclosed in its first application at the Kenwood Observatory (Chicago, 1892) a new and unexplored region of the sun's atmosphere.
Generated by solar flares or large solar prominences, "coronal transients" (also called coronal mass ejections) are sometimes released.
Lyot (1931) for the purpose of observing the corona of the sun and solar prominences occurring in the chromosphere. Because of the intense light of the sun, the corona and chromosphere can ordinarily be seen only during a total eclipse.
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.
The Sun's faint corona will be visible, and even the chromosphere, solar prominences, and possibly even a solar flare may be visible.
Solar prominences are visible as part of the corona during a total solar eclipse.
He took this instrument to Spain and for the first time was able to photograph solar prominences, which can only be seen during a solar eclipse.
These loops, solar prominences, occasionally collide and short-circuit each other. This is what causes solar flares. These flares release vast amounts of high-energy particles and gases and are incredibly hot (they range from 3.
Prominence
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.
The first astrophysicist, invented the spectroheliograph allowing photography of solar prominences in daylight, discovered magnetic fields in sunspots, planned and completed the 200-inch Mt. Palomar telescope.
It has studied the sun's magnetism, solar prominences and coronal mass ejections (orbiting over the south pole of the Sun in 1994 and over the north pole in 1995), and will will complete a second solar orbit in December, 2001.

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).
The Moon's black disc will look almost like a hole in the sky, and peeking around the black disc should be a number of pinkish solar prominences, gigantic explosions of hot hydrogen gas that boil off from the Sun in spectacular arching shapes.
