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. D. Stratwarm: None E.
