WARNING: Geomagnetic K-index of 7 or greater (G3 or Greater), Space Weather Prediction Center (NOAA)

"NOAA Scale: G3 or greater - Strong to Extreme

- 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."
