This still (below) from NASA's Solar Dynamics Observatory (SDO) caught the action in freeze-frame splendor when the Sun popped off two events at once on Jan. 28, 2011. A filament on the left side became unstable and erupted, while an M-1 flare (mid-sized) and a Coronal Mass Ejection on the right blasted into space. The movie (above), taken Jan. 26-28, 2011, shows several other flashes and bursts from the active region on the right as well. Neither event is headed towards Earth.
