Prominence

</dt>
A filamentlike protuberance from the chromosphere of the sun. See flocculi. Compare flare. </dd>
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 6,000 to 12,000 kilometers thick, 60,000 kilometers high, and 200,000 kilometers long. [[/a>|/a> ]]
