Description	A picture of the solar corona taken with the LASCO C1 coronagraph.
Source	The image appears on a website entitled, "File:LASCO C1a.png" at url=https://commons.wikimedia.org/wiki/File:LASCO_C1a.png, originally adapted from url=http://lasco-www.nrl.navy.mil/~Xreiser/C1_dopp.html.

Rationale	No free licensed or public domain alternatives known to exist to show a picture of the solar corona taken with the LASCO C1 coronagraph which employed a tunable Fabry-Perot interferometer to recover scans of the solar corona at a number of wavelengths near the FeXIV green line. The picture is a color coded image of the doppler shift of the line, which may be associated with the coronal plasma velocity towards or away from the satellite camera.
