B.  Proton Events:  The greater than 10 MeV proton flux at
geosynchronous orbit exceeded the 10 pfu threshold at 17/1715Z,
reached a maximum of 136 pfu at 18/0600Z, and is still ongoing at
the time of this report.
C.  Geomagnetic Activity Summary:  The geomagnetic field was at quiet
to unsettled levels.  Two active periods were observed at the
Boulder magnetometer, and isolated active and minor storm periods
were observed at high latitudes.
