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.

I saw it for the first time during May's storm, which made bright red/purple ones above the Wyoming-Colorado border after 22:00. They're remarkable and if you're within the right latitude range it's worth finding the nearest dark sky area to watch them: https://www.darkskymap.com/nightSkyBrightness
