Prominensa occur in layers in the solar photosphere and move out into the solar corona. If the corona is a gas that has been ionized becomes very hot, called plasma, which did not show the light, prominensa contains a cooler plasma.
Prominensa typically protrude up to thousands of kilometers, the largest ever observed to appear in 1997 with a length of about 350 000 kilometers - about 28 times diameter of the earth. The mass of material contained within prominensa weighing up to 100 billion tons.
