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.
