Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; Increased drag on low Earth-orbit satellites is possible.
Radio – HF (High frequency) radio propagation can fade at Higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.
