Latest Space Weather News and Updates
December 11, 2017 @ 16:45 UTC
Coronal Hole Stream
An elevated coronal hole solar wind stream is now beginning to move past Earth. Enhanced geomagnetic activity will be possible at higher latitudes. Sky watchers in the polar zones should be alert for visible aurora once dark outside.

Aurora Watch
As expected, a coronal hole solar wind stream is now beginning to move past Earth. Enhanced geomagnetic activity (Kp4) is currently being observed at higher latitudes. A Minor (G1) to Moderate (G2) geomagnetic storm watch will be in effect for the next 24-36 hours as the stream continues to disturb our geomagnetic field. High latitude aurora sky watchers should be alert once dark outside.

December 2, 2017 @ 00:45 UTC
Geomagnetic Storm Watch Beginning Dec. 4
Good evening. Coronal Hole #45 is now beginning to face our planet. A high speed solar wind stream flowing from this zone is expected to reach our planet beginning December 4th and could lead to minor (G1) geomagnetic storming at higher latitudes. An isolated period of Moderate (G2) storming may also be possible, but we will have to wait until the onset of the CH stream and monitor conditions at that point. More updates in the days ahead.
