Proton Events: None. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels for most of the day. Conditions became enhanced late in the day when active levels were reached during the 12/1800-2100 UTC synoptic period and minor storm levels were reached during the 12/2100-2359 UTC synoptic period, mainly due to CIR and CH HSS effects. D. Stratwarm: Not Available E.
