Proton Events: The greater than 100 MeV proton event at geosynchronous orbit that began at 13/1810Z has so far reached a peak of 1.89 pfu and the event remains in progress. The greater than 10 MeV proton event that began at 13/1810Z has so far reached a peak of 469 pfu and the event remains in progress as of the close of the period. C. Geomagnetic Activity Summary: Field activity was mostly quiet to unsettled in the mid latitudes with active periods at high latitudes. D. Stratwarm: Not Available E.
