#15 según la escala del space weather prediction center, G2.
De las geomagnéticas, la escala va de G1 (leve) a G5 (extrema)
A ese nivel hasta sería posible ver auroras boreales en nuestra latitud peninsular. Pero parece que el mayor pico se prevee a las 12 UTC así que, no se yo...

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.
