"Soon after the instruments opened their doors, the Sun began performing for SDO with this beautiful prominence eruption. This AIA data is from March 30, 2010, showing a wavelength band that is centered around 304 �. This extreme ultraviolet emission line is from singly ionized Helium, or He II, and corresponds to a temperature of approx. 50,000 degrees Celsius."
