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 active levels. Elevated solar wind speed near 700 km/s combined with a Bz near negative 5 nT resulted in active conditions. D. Stratwarm: STRATWARM ALERT/SUNDAY/STRATWARM EXISTS DISTURBED WAVE NUMBER TWO PATTERN OF THE CIRCULATION AND OF THE TEMPERATURE DISTRIBUTION.
