Space Weather Message Code: WARK06 Serial Number: 662 Issue Time: 2026 Jun 05 1721 UTC EXTENDED WARNING: Geomagnetic K-index of 6 expected Extension to Serial Number: 661 Valid From: 2026 Jun 05 1437 UTC Now Valid Until: 2026 Jun 06 0300 UTC Warning Condition: Persistence 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.

Space Weather Message Code: WARK05 Serial Number: 2239 Issue Time: 2026 Jun 05 1719 UTC EXTENDED WARNING: Geomagnetic K-index of 5 expected Extension to Serial Number: 2238 Valid From: 2026 Jun 05 1228 UTC Now Valid Until: 2026 Jun 06 0600 UTC Warning Condition: Persistence NOAA Scale: G1 - Minor NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact primarily poleward of 60 degrees Geomagnetic Latitude. Induced Currents - Weak power grid fluctuations can occur. Spacecraft - Minor impact on satellite operations possible. Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.
