Latest Space Weather News and Updates
September 10, 2018 @ 20:10 UTC
Geomagnetic Storm Warning / Aurora Watch
The anticipated coronal hole stream is now beginning to move past Earth. The interplanetary magnetic field (Bz) component carried past our planet via the solar wind is pointing south, a condition that favors elevated geomagnetic conditions. Minor (G1) to isolated Moderate (G2) storming will be possible at higher latitudes during the next 24-48 hours. Sky watchers should be alert for visible aurora should local weather and light conditions allow.

September 8, 2018 @ 13:35 UTC
Coronal Hole #23 (UPDATED)
The next coronal hole in line (23) is now beginning to face our planet. A solar wind stream flowing from this narrow opening in the sun's atmosphere is expected to reach Earth sometime after September 11th. A minor geomagnetic enhancement will be possible at higher latitudes. More updates in the days ahead. Image below by SDO/AIA.

UPDATE @ 04:40 UTC (Sep 9): The coronal hole stream is predicted to reach Earth by late on September 10th. Minor (G1) geomagnetic storming will be possible with a chance for an isolated period of Moderate (G2) storming. An aurora watch will be in effect for the next 48-72 hours.
