Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: The greater than 10 MeV proton event that began at 10/2045 utc, reached a tentative maximum of 91 pfu at 11/0530 UTC. The flux is slowly declining. C. Geomagnetic Activity Summary: The geomagnetic field was at unsettled to active levels, due to a high speed solar wind stream. D. Stratwarm: None E.
