Huge Solar Eruption! M2.5 solar flare, June 7, 2011

Source: sdoisgo.blogspot.com

SDO observed an enormous prominence this morning associated with an M2.5 solar flare that peaked at 6:41 UT. This is a very large explosion of cool gas on the Sun. It is somewhat unique that there seems to be even cooler material at temperatures less than 80,000K at many places this eruption (Thanks Harry Warren for noticing this!) - as seen by the darker regions in front that absorb the other enhanced emissions formed behind the dark regions in this channel. Material from this region looks as though it mostly falls back to the solar surface covering an area of almost half of the solar surface!
