Solar Dynamics Observatory

The Sun performs for SDO – AIA
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 Å. This extreme ultraviolet emission line is from singly ionized Helium, or He II, and corresponds to a temperature of approx. 50,000 degrees Celsius. The second movie shows a prominence with larger field of view.

Solar observing in more detail…..stay tuned.
