B.  Proton Events:  The greater than 10 MeV proton flux at
geosynchronous orbit reached the 10 pfu event threshold at 11/1055Z,
and the 100 pfu event threshold at 11/1630Z, reaching a peak value
of 114 pfu at 11/1645Z.  The greater than 10 MeV proton event is
still in progress.  The greater than 100 MeV proton flux at
geosynchronous orbit reached the 1 pfu event threshold at 11/0940Z
with a peak value of 2 pfu at 11/1400Z, and ended at 11/1955Z.
C.  Geomagnetic Activity Summary:  The geomagnetic field was quiet.
