Arvisp writes "As predicted, the a 'mega-filament' of solar magnetism erupted on Dec. 6th, producing a blast of epic proportions. NASA's Solar Dynamics Observatory recorded the action as the 700,000-km long structure lifted off the stellar surface and--snap!!--hurled itself into space. The eruption produced a bright coronal mass ejection (CME) observed by the STEREO-A spacecraft: video. Earth was not in the line of fire; the cloud should sail wide of our planet. Earth-effects might be limited to pretty pictures."
