Update 10/1/13 10:30 est:. Geomagnetic Sudden Impulse detected at 20:13 10/2/13 UTC. Deviation 72nt, Station Boulder. Original post below: WATCH: Geomagnetic Storm Category G2 Predicted A impressive large CME was ejected earlier this week and we are starting to feel the effects, Read about this spectacular CME and see video of it. Highest Storm Level Predicted by Day: Oct 02: G1 (Minor) Oct 03: G2 (Moderate) Oct 04: 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.
