B.  Proton Events:  None
C.  Geomagnetic Activity Summary:  The geomagnetic field was quiet to
active.  A single active period was observed during 03/0300-0600
UTC, as coronal hole effects diminished, and quiet to unsettled
conditions predominated thereafter.  The greater than 2 MeV electron
flux at geosynchronous orbit showed moderate enhancement today, but
remained below event threshold.
