Proton Events: None. C. Geomagnetic Activity Summary: He geomagnetic field was at unsettled to active levels during most of the summary period, with minor storm conditions occurring the last synoptic period of the day. The enhanced activity was the result of the Earths geomagnetic field responding to the increased total magnetic field strength and sustained -Bz due to the transient feature. D. Stratwarm: Not Available E.
