WARNING: Geomagnetic K-index of 6 (G2)

Space Weather Message Code: WARK06 Serial Number: 393 Issue Time: 2017 Aug 31 1336 UTC
WARNING: Geomagnetic K-Index of 6 expected Valid From: 2017 Aug 31 1337 UTC Valid To: 2017 Aug 31 1800 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.

SPACE WEATHER ADVISORY OUTLOOK #17-35 2017 August 27 at 9:37 p.m. MDT (2017 August 28 0337 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For August 21-27
G1 (Minor) geomagnetic storm levels were observed on 22-23 August while G2 (Moderate) geomagnetic storm levels were observed on 22 August due to coronal hole high speed stream effects coupled with prolong periods of southward Bz.
Outlook For August 28-September 3
G1 (Minor) geomagnetic storm levels are likely on 31 August due to the arrival of a positive polarity coronal hole high speed stream.
