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 quiet to active. Active periods were due to the effects of sustained periods of southward Bz. Solar wind speed at ACE showed an increase from 450 km/s to 550 km/s at approximately 1600 UTC. D. Stratwarm: None. E.
