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. 50000 degrees Celsius. The second movie shows a prominence with larger field of view
