Watch (111) 1530 20 Apr 2014

19 min 43 sec ago
Watch (111): Geomagnetic Storm Category G2 Predicted Highest Storm Level Predicted by Day: Apr 20: G2 (Moderate) Apr 21: G1 (Minor) Apr 22: 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.
