ALERT: Geomagnetic K-index of 6
Threshold Reached: 2017 Sep 27 2220 UTC
Synoptic Period: 2100-2400 UTC

Active Warning: Yes
NOAA Scale: G2 – Moderate

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.
