ALERT: Geomagnetic K-index of 6 (G2)

Space Weather Message Code: ALTK06 Serial Number: 461 Issue Time: 2018 Apr 20 1045 UTC
ALERT: Geomagnetic K-index of 6 Threshold Reached: 2018 Apr 20 1044 UTC Synoptic Period: 0900-1200 UTC Active Warning: Yes 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.
