Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0332 0332 0332 120 B. Proton Events: Proton levels are high. The greater than 10 MeV proton flux event that began at 23/0530Z, reached a new maximum of 6310 pfu at 24/1530Z. Flux values since the onset of this event have decreased below 1000 pfu and are currently at 744 pfu. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels with isolated minor to major storm periods. D. Stratwarm: Not Available E.
