ALMOST-X FLARE: Active sunspot AR2242 erupted on Dec. 17th, producing an M9-class solar flare. The explosion caused a brief HF radio blackout on the daylitt side of Earth. The event was minor, however, and would have been noticed by only a small number of mariners and ham radio operators. Of greater interest is the CME. SOHO coronagraphs have detected a bright and massive cloud of plasma emerging from the blast site (image 2). The bulk of the CME appears to be traveling south of the sun-Earth line, so a direct hit is unlikely. However, our planet could receive a glancing blow from the cloud a few days hence. Stay tuned for updates. More strong flares could be in the offing. AR2242 is growing and it has an unstable beta-gamma-delta magnetic field poised to explode again. NOAA forecasters estimate a 55% chance of M-flares and a 10% chance of X-flares on Dec. 17th. via SpaceWeather
