WARNING: Geomagnetic K-index of 6 (G2)

Space Weather Message Code: WARK06 Serial Number: 560 Issue Time: 2025 Feb 15 1034 UTC WARNING: Geomagnetic K-Index of 6 expected Valid From: 2025 Feb 15 1030 UTC Valid To: 2025 Feb 15 1500 UTC Warning Condition: Onset NOAA Scale: G2 - Moderate 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.
