B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field reached minor to major storm levels with severe storms at high latitudes due to continued effects from the 05 Oct CME. Unsettled to active periods were observed from 09/1200-2100Z followed by another minor storm period to end the day due to effects from a coronal hole high speed wind stream.
