ALERT: Geomagnetic K-index of 6



Space Weather Message Code: ALTK06
Serial Number: 436
Issue Time: 2017 Jul 16 1455 UTC


ALERT: Geomagnetic K-index of 6
Threshold Reached: 2017 Jul 16 1454 UTC
Synoptic Period: 1200-1500 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate

NOAA Space Weather Scale descriptions can be found at

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.
