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 mostly quiet to unsettled with an isolated active period between 08/1200 - 1500Z. D. Stratwarm: STRATWARM ALERT / SATURDAY / STRATWARM EXISTS. IN THE MIDDLE AND UPPER STRATOSPHERE, STILL DISTURBED TEMPERATURE DISTRIBUTION WITH A DECAYING WARM REGION OVER NORTHERN SIBERIA. THIS STILL LEADS TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE FROM 3 TO 1 HPA. E.
