CANCELLED WARNING: Geomagnetic K-index of 6 (G2)
Space Weather Message Code: WARK06 Serial Number: 565 Issue Time: 2025 Mar 09 2320 UTC CANCEL WARNING: Geomagnetic K-Index of 6 expected Cancel Serial Number: 564 Original Issue Time: 2025 Mar 09 0423 UTC Comment: The previous extention was an error. The conditions for this level of geomagnetic activity no longer exist. 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.
