Proton Events: The greater than 10 MeV proton flux at geosynchronous orbit was enhanced following the X1/2B flare at 27/1748 UTC, reaching a maximum flux of 3 pfu at 29/2230 UTC. Flux is returning to normal levels. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet levels. D. Stratwarm: Not Available E.
