Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0724 0741 0750 9657 N19E67 C7.0 Sf 125 12 II 1046 1113 1149 9653 S28E08 M1.4 2f 25 130 II/IV B. Proton Events: The greater than 10 MeV proton flux at geosynchronous orbit remained at elevated levels but below the proton event threshold of 10 pfu. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels. High speed stream effects are believed to be responsible for the elevated field levels. D. Stratwarm: None E.
