Earth-directed solar flare could bring geomagnetic storms this weekend
Spaceweather.com report that an active sunspot 1401 erupted yesterday, January 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.
