MAGNETIC ERUPTION : On Dec. 14th around 1530 UT, a filament of magnetism lifted up from the surface of the sun and--snap!--erupted. NASA's Solar Dynamics Observatory recorded the action.
The blast produced an hours-long C2-class solar flare and hurled a magnificent CME into space: SOHO movie. The expanding cloud is not heading directly toward Earth, but it might deliver a glancing blow to our planet's magnetic field two or three days hence. High latitude sky watchers should be alert for auroras.
