B. Proton Events
A greater than 10 MeV proton flux greater than 10 pfu event continues. The event began at 23/2330Z, reached a maximum of 1660 pfu at 23/0650Z, fell below the 1000 pfu threshold at 23/1040Z and ended the day at 180 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled.
D. Stratwarm

F. Comments
  >2MeV electron data suspect because of proton
contamination.  GOES-15 particle data is being used because of a
GOES-13 outage.
