Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0142 0151 0202 0280 S05W43 C8.7 1f 7900 56 II B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels. A single isolated active period was observed at higher latitudes between 12/1500 to 1800Z. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels again today. D. Stratwarm: STRATWARM ALERT/WEDNESDAY/STRATWARM EXISTS. 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 E.
