Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field activity was at predominantly quiet to unsettled levels with an isolated period of active conditions between 18/1500-1800 UTC due in part to the elevated solar wind speeds (550-650 km/s). The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels today. D. Stratwarm: None E.
