C. Geomagnetic Activity Summary
The geomagnetic field was at unsettled to minor storm levels early in the day, then at quiet to unsettled levels thereafter. The isolated minor storm period was observed at higher latitudes during 10/0300-0600 UTC, in probable association with a sustained period of southward Bz during that time.
