WATCH: Geomagnetic Storm Category G2 Predicted
Highest Storm Level Predicted by Day
Oct 27: None (Below G1) Oct 28: G2 (Moderate) Oct 29: G1 (Minor)
THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
Comment: Upgraded 28 Oct to G2 and added G1 for 29 Oct.
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.
