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. Coronagraph images from the Solar and Heliospheric Observatory (SOHO) confirm that the explosion hurled a CME into space. A first look at the data suggests that the bulk of the CME will miss Earth, but there appears to be an Earth-directed component as well. A fraction of the CME could hit our planet on May 28th or 29th. Computer modeling by NOAA analysts will soon refine the arrival time
NASA’s Solar Dynamics Observatory recorded the blast:
