B.  Proton Events:  A greater than 100 MeV proton event commenced at
13/0300 UTC, reached maximum at 13/0525 UTC with 88.7 pfu and ended
at 14/1150 UTC.  The greater than 10 MeV event that started 13/0310
UTC is still in progress with current levels increasing due to
enhancement from an X1.5 flare from Region 930  (S05W47).  Another
greater than 100 MeV proton event commenced at 14/2255 UTC .
C.  Geomagnetic Activity Summary:  The geomagnetic field reached
major to severe storm levels.  The ACE satellite observed the shock
from the 13 December CME at 14/1356 UTC.  A sudden impulse was
observed at the Boulder magnetometer at 14/1416 UTC with a deviation
of 26 nT.  Periods of major to severe storming occurred between
14/1200 UTC and 14/1800 UTC.  Solar wind speed is currently 900
km/s.
