Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1735 1750 1759 0540 M5.0 270000 580 II B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. A coronal hole high speed stream is responsible for the weak disturbed periods. The IMF Bz was predominantly northward which offset the geomagnetic effects of the high speed flow. D. Stratwarm: None E.
