> 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.
