Space Weather reports that one of the largest solar prominences in years erupted from the sun's northwestern limb yesterday, April 13. "The massive plasma-filled structure rose up and burst during a ~2 hour period around 0900 UT on April 13th." Observers in Europe had the best view, and this photo was shot by Jo Dahlmans of Ulestraten, Netherlands, using his Coronado Personal Solar Telescope. "The eruption hurled a bright coronal mass ejection (CME, movie) into space. The expanding cloud could deliver a glancing blow to Earth's magnetic field around April 15th. NOAA forecasters estimate a 35% chance of polar geomagnetic activity when the CME arrives."
