Jun 24: None (Below G1) Jun 25: G2 (Moderate) Jun 26: G1 (Minor)
THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
Comment: Recurrent, negative polarity coronal hole high speed stream influence is likely to bring minor to moderate geomagnetic storming 25-26 Jun.
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.
