Geomagnetic Storm Category G2 Predicted
June 14, 2026 8:30 AM UTC
Space Weather Message Code: WATA30 Serial Number: 276 Issue Time: 2026 Jun 14 0830 UTC CANCELLED WATCH: Geomagnetic Storm Category G2 Predicted Cancel Serial Number: 275 Original Issued Time: 2026 Jun 11 2029 UTC G1 (Minor) geomagnetic storm conditions are no longer expected. G1 (Minor) geomagnetic storm conditions are no longer expected. NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation 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.
