Solar Eclipse 1991 from Hawaii
A total solar eclipse on July 11, 1991 as seen from Mauna Loa, Hawaii. This photo was taken by a team from NCAR's High Altitude Observatory (HAO) and from Rhodes College in Memphis, Tennesee. The fuzzy glow around the Sun in this picture is the solar corona, the Sun's upper atmosphere. There are also two solar prominences visible in this photo, on the right and left edges of the Sun's disk. Prominences are enormous eruptions of plasma in the Sun's atmosphere.
