Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1142 1142 1143 270 1604 1604 1604 100 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled with isolated active periods at higher latitudes. A period (04-12Z) of mostly southward orientation in the IMF was responsible for the more disturbed periods. D. Stratwarm: STRATWARM ALERT/TUESDAY/STRATWARM EXISTS. NEW WARM PULS, STRONGEST IN THE UPPER STRATOSPHERE, BUT TEMPERATURE HAS INCREASED MORE THAN 30 KELVIN ALSO AT 10 HPA AND BELOW WITHIN ONE WEEK OVER NORTHERN SIBERIA. REVERSAL OF THE TEMPERATURE GRADIENT BETWEEN 60N AND THE NORTH POLE EXPECTED WITHIN THE NEXT 3 DAYS FROM 50H PA UP 1HPA. E.
