A DEAD SUNSPOT EXPLODES (UPDATED): A magnetic filament snaking through the corpse of decayed sunspot AR3016 erupted on May 25th (1824 UT), producing a M1-class solar flare. NASA's Solar Dynamics Observatory recorded the blast:
Coronagraph images from the Solar and Heliospheric Observatory (SOHO) confirm that the explosion hurled a CME into space: movie. The bulk of the CME will miss Earth, passing just ahead and south of our planet. However, a fraction of the cloud will hit. NOAA analysts expect a glancing blow to Earth's magnetosphere on May 28th with a chance of minor G1-class geomagnetic storms.
