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.

SWPC is currently experiencing problems with the email product delivery system; users are reporting missing or delayed scheduled products. Additionally, as part of testing, a geomagnetic storm warning product noting G3 or higher level storming expected was inadvertently issued and then canceled. Active troubleshooting is ongoing now and updates will be provided, when available. No significant space weather is forecast at this time.
