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 unsettled. An interplanetary shock was observed at ACE at 25/0058Z. The field remained quiet to unsettled following this shock as Bz remained northward for the duration of this weak transient passage. D. Stratwarm: None E.
