Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled with isolated active levels late in the period. Extended periods of southward IMF were observed this period, but the potential impact on the geomagnetic field was offset by the very low solar wind speeds (260 -320 km/s). D. Stratwarm: None E.
