Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic
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 Washinton state.
