Sunspot group AR9591 unleashed a powerful X5-class solar flare at 1645 UT (1245 EDT) on August 25th. The explosion triggered an hour-long radio blackout over parts of Europe, Africa, and the Americas. It also hurled a brilliant halo coronal mass ejection into space. Forecasters estimate a 20% chance of severe geomagnetic activity when the expanding cloud hits Earth's magnetosphere late Sunday or (more likely) Monday. Sky watchers above ~45 degrees geomagnetic latitude should be alert for auroras around local midnight.
