Important notice about STEREO Behind

CMEs and a Flare


The Sun blasted out two coronal mass ejections (CMEs) and a flare on March 25, 2008. STEREO's COR 2 coronagraph (Ahead) caught the action. In the video clip, a smaller CME first bursts off to the right. After an 8-hour data gap, a flare and associated CME blast off to the left in a much larger bulbous cloud of particles. The flare, a moderate M-class event, is the largest STEREO has seen this year.
