Earth Directed CME...G2 Geomagnetic Storm Forecasted!
a look at the Predcition Model from iSWA, as we already covered NOAAs...In this ENLIL Spiral, the Radial Velocity is Forecasted to be over 900 km/s, and will Arrive late on the 16 of March and into the 17th...
Heres the Updated Official Alert/Warning for this Event:
Space Weather Message Code: WATA30
Serial Number: 101
Issue Time: 2013 Mar 15 1712 UTC

Highest Storm Level Predicted by Day:
Mar 16: G1 (Minor) Mar 17: G2 (Moderate) Mar 18: None (Below G1)
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.
