Proton Events: The greater than 10 MeV proton event ended at 12/1040 UTC. C. Geomagnetic Activity Summary: The geomagnetic field was unsettled to active with isolated minor storm periods. Activity was due to enhanced solar wind speeds coupled with prolonged periods of southward Bz. D. Stratwarm: Not Available E.
