WARNING: Geomagnetic K-index of 6 (G2)

Space Weather Message Code: WARK06 Serial Number: 413 Issue Time: 2017 Dec 05 1417 UTC
WARNING: Geomagnetic K-Index of 6 expected Valid From: 2017 Dec 05 1420 UTC Valid To: 2017 Dec 05 2100 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.
