WSA/ENLIL modeling of the event shows a partially Earth-directed component that is expected to impact the geomagnetic field early to midday on November 10 causing active to major storm conditions (G1-G2, Minor to Moderate). 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. Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. HF (high frequency) radio propagation can fade at higher latitudes. Aurora may be seen as low as New York to Wisconsin to Washington state.
