[Barry Porter]

ALERT: Geomagnetic K-index of 8 
Threshold Reached: 2017 Sep 07 2350 UTC 
Synoptic Period: 2100-2400 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. 

Aurora - Aurora may be seen as low as Alabama and northern California.
