EARTH-DIRECTED FLARE: Active sunspot 1401 erupted today, Jan. 19th, for more than an hour around 16:00 UT. The long-duration blast produced an M3-class solar flare and a CME that appears to be heading toward Earth. Forecasters say strong geomagnetic storms are possible when the cloud arrives during the late hours of Jan. 21st. High-latitude (and possibly middle-latitude) sky watchers should be alert for auroras this weekend. Check http://spaceweather.com for movies and updates.
DON'T MISS THE STORM: Would you like a call when geomagnetic storms are in progress? Storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
I know I always want to know in advance if I should be on the lookout for northern lights, so just in case someone else is out there who'd like to know, I thought I'd share. Charge up those camera batteries and get out the tripods!
