Coronal Mass Ejection!

Solar wind gusts have triggered auroras off and on since Oct. 23rd.  There could be even more geomagnetic activity this weekend if a coronal mass ejection (CME) sweeps past our planet as expected. The CME billowed away from the Sun on Oct. 25th not long after a spectacular prominence
erupted--the movies at spaceweather.com are a must-see!
