B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to active. Solar wind speed was near 600 km/s early in the period, which accounted for the active periods. Speed declined to near 450 km/s by the end of the period. The field responded to the declining solar wind speed by returning to mostly quiet levels.
