POSSIBLE EARTH-DIRECTED CME: A magnetic filament snaking around sunspot AR1692 erupted on March 15th at about 0600 UT. The slow explosion, which took hours to unfold, produced an M1-class solar flare and a bright CME. SOHO (the Solar and Heliospheric Observatory) and STEREO-B spacecraft captured the CME just as it was leaving the sun: http://www.spaceweather.com/
