B.  Proton Events:  None
C.  Geomagnetic Activity Summary:  The geomagnetic field was quiet to
unsettled.  At 04/1335 UTC, the greater than 2 MeV electron flux
exceeded event threshold at GOES-8 in geosynchronous orbit (75W).
Flux levels remained above 1000 pfu for about nine hours, reaching a
max of about 1960 pfu near local noon.
D.  Stratwarm:  None
