Issue Time: 2017 Sep 08 1306 UTC

ALERT: Geomagnetic K-index of 8
Threshold Reached: 2017 Sep 08 1304 UTC
Synoptic Period: 1200-1500 UTC

Active Warning: Yes
NOAA Scale: G4 – Severe

Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude.
Induced Currents – Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify.
Spacecraft – Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur.
Navigation – Satellite navigation (GPS) degraded or inoperable for hours.
Radio – HF (high frequency) radio propagation sporadic or blacked out.
