X1.2 CME to deliver a direct blow to Earth: UPDATED

via Solarham.net

An early CME prediction model has been released following the X1.2 solar flare event on Tuesday afternoon. The model is predicting the fast moving CME to deliver an almost direct blow to our geomagnetic field late on January 8th (Wednesday), early January 9th (Thursday) UTC time. Keep in mind these models are estimated and may be updated once more data becomes available. Nonetheless, geomagnetic storming will be possible in the days ahead. This is good news for sky watchers at high latitudes. More updates to follow.

Space Weather Message Code: WATA30
Serial Number: 109
Issue Time: 2014 Jan 07 2127 UTC


WATCH: Geomagnetic Storm Category G2 Predicted
Highest Storm Level Predicted by Day:
Jan 08: None (Below G1) Jan 09: G2 (Moderate) Jan 10: G1 (Minor)
THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
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.
