Geomagnetic Storm Category G2 Predicted

Moderate Activity Continues
Good morning. Below is an updated image of the visible solar disk on Thursday. Solar activity remains at moderate levels with a number of low level M-Flares detected around sunspot 1974. They include an M1.8 at 01:40 UTC, M1.0 at 02:51 UTC, M1.7 at 06:07 UTC and finally an M1 at 08:11 UTC. The geoeffective active region continues to maintain a complex Beta-Gamma-Delta magnetic configuration and may continue to produce M-Class solar flares during the next 24 hours. There is also a lower chance for an isolated X-Class event. All other visible Earth facing regions remain stable. Stay Tuned to for the latest information.

Weekend Aurora Watch
The solar wind prediction model released by NOAA has been updated to include a pair of coronal mass ejections with potential Earth directed components. A model released by the Goddard Space Flight Center is also updated to include a halo CME from earlier this morning. An impact to our geomagnetic field will be possible this weekend (Feb 15) and could lead to aurora displays at high latitudes.
WATCH: Geomagnetic Storm Category G2 Predicted
Highest Storm Level Predicted by Day:
Feb 13: None (Below G1) Feb 14: G1 (Minor) Feb 15: G2 (Moderate)
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.
