Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0531 0531 0531 160 1347 1347 1347 100 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. The recurrent high speed coronal hole stream developed late last period and produced mostly active conditions during local nighttime hours. D. Stratwarm: None E.
