Minor Geomagnetic Storms Likely Dec. 7-10

Space Weather News for Dec. 7, 2016 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are likely for the next three to four days as Earth passes through a stream of high-speed solar wind. A type of shock wave at the leading edge of the stream called a "co-rotating interaction region" (CIR) could spark a display of bright Arctic auroras as early as Dec. 7-8.

Coronal holes are regions where the sun's magnetic field opens up and allows solar wind to escape. Share Tweet Forward Copyright © 2016 Spaceweather.com, All rights reserved.
