Solar Prominences (2) ...
The left figure below shows a prominence on the edge of the Sun
photographed in H-alpha light
by the Big Bear Solar Observatory on October 3, 1996.
The figure below right shows the total solar eclipse of August, 1999, as imaged by
Pavel and Roman Cagas. Several red prominences are obvious
on the limb of the Sun.
The bright red color of prominences is associated with strong emission of Balmer
H-alpha radiation.
