Space Weather Message Code: ALTK06 Serial Number: 435 Issue Time: 2017 May 28 0824 UTC
ALERT: Geomagnetic K-index of 6 Threshold Reached: 2017 May 28 0823 UTC Synoptic Period: 0600-0900 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.

NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation
Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude. Induced Currents – Power system voltage irregularities possible, false alarms may be triggered on some protection devices. Spacecraft – Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur. Navigation – Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur. Radio – HF (high frequency) radio may be intermittent. Aurora – Aurora may be seen as low as Pennsylvania to Iowa to Oregon. Thank you for using the Product Subscription Service.
