A moderate G2 geomagnetic storm watch has been issued for November - TopicsExpress



          

A moderate G2 geomagnetic storm watch has been issued for November 10th. The watch was added as a result of the X1.6 flare and CME event from Friday. When watching the attached video courtesy of LASCO C2 and C3, you can clearly see that a bulk of plasma is traveling to the north and east and away from our planet. Despite this, sky watchers at high latitudes should remain alert. I do not personally expect G2 storm conditions to materialize, but then again, we have been surprised in the past. WATCH: Geomagnetic Storm Category G2 Predicted Highest Storm Level Predicted by Day: Nov 08: None (Below G1) Nov 09: None (Below G1) Nov 10: G2 (Moderate) 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. solarham.net/data/events/nov7_2014_x1.6/index.htm
