G1 (Minor) Geomagnetic Storms still possible overnight

G1 (Minor) Geomagnetic Storms still possible overnight
published: Wednesday, August 19, 2015 14:55 UTC

The CME that produced G3 (Strong) geomagnetic storms on August 15th, 2015 seems to have moved past the Earth. However, we are still under the influence of a high speed solar wind stream from coronal hole 88 (CH 88) and G1 (Minor) geomagnetic storms are possible in the evening to overnight hours. A G1 Watch has been issued for the UTC day of August 17th to reflect this activity. Stay tuned here for updates!
