Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels. The greater than 2 MeV electron fluxes at geosynchronous orbit reached moderate levels today. D. Stratwarm: STRATWARM ALERT / THURSDAY / STRATWARM EXITS. IN THE MIDDLE AND UPPER STRATOSPHERE, SLIGHTLY DISTURBED TEMPERATURE DISTRIBUTION WITH A WARM REGION OVER SIBERIA LEADING TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE FROM 5 TO 1 HPA.
