A beautiful prominence eruption shot off the east limb (left side) of the sun on Monday, April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare did occur at the same time, though it was not aimed toward Earth. This event was seen by NASA’s SDO satellite.
