SPACE WEATHER ADVISORY OUTLOOK #17-31 2017 July 30 at 8:56 p.m. MDT (2017 July 31 0256 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For July 24-30
No space weather storms were observed for the summary period.
Outlook For July 31-August 6
G1 (Minor) Geomagntic Storms are likely on 04-05 Aug due to coronal hole influence.
A chance for R1 (Minor) Radio Blackouts exists on 31 Jul – 06 Aug due to potential flare activity from an active region rotating onto the visible solar disk.

ALERT: Geomagnetic K-index of 6 (G2)

Space Weather Message Code: ALTK06 Serial Number: 438 Issue Time: 2017 Jul 17 1642 UTC
ALERT: Geomagnetic K-index of 6 Threshold Reached: 2017 Jul 17 1642 UTC Synoptic Period: 1500-1800 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.

**** SPACE WEATHER OUTLOOK ****
Summary For July 10-16
An R1 (Minor) Radio Blackout was observed on 14 July from active Region 2665. This event produced an Earth-directed CME. An S1 (Minor) Solar Radiation Storm was observed on 14 – 15 July due to the R1 Radio Blackout from 14 July. G1 (Minor) and G2 (Moderate) Geomagnetic Storms were observed on 16 July as a result of the 14 July CME.
Outlook For July 17-23
G1-G2 (Minor-Moderate) Geomagntic Storms are likely on 17 July due to continued effects from the 14 July CME. A chance for S1 (Minor) Solar Radiation Storms exists for 17-19 July due to the potential for siginificant flare activity from Region 2665. A chance for R1 (Minor) Radio Blackouts exists for 17-19 July due to the potential for siginificant flare activity from Region 2665.
