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.


My bad luck. I just spent a week in the Hebrides at about 57N with no sign
