Proton Events: Proton levels are moderate. The greater than 10 MeV proton flux event that began at 23/0530Z continues to decrease. Flux values have stayed above the 100 pfu level throughout the day. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels with an isolated minor storm period. D. Stratwarm: Not Available E.
