Flash Flare

An M6 flare (medium-sized) associated with a coronal mass ejection blasted out from the Sun and appears to be headed in the general direction of Earth (Aug. 3, 2011). The still show the characteristic spreading of light caused by the brightness of the flare as observed in extreme ultraviolet light. The movie covers about two hours of activity. If this particle cloud bumps Earth in a few days, it would cause bright auroras and could possibly upset electronic equipment,
especially in space.
