Just passing along a message from my local radio club

NOAA Space Weather Scale descriptions can be found at

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.

Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.

Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.

Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.

Radio - HF (high frequency) radio may be intermittent.

Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon.

For those interested in solar updates like this, as I am too, check out the Space Weather App for iPhone (and maybe Android?) by Stellar North LLC. Daily updates, push alerts, content mirrors the data above. Good stuff.
