Proton Events: The greater than 10 MeV proton event that began at 02/1105Z has thus far had a maximum of 1570 pfu, which occurred at 03/0815Z and has recently been ranging between 400 and 800 pfu's at the time of this writing. The greater than 100 MeV proton event began at 02/1740Z, reached a maximum of 49 pfu at 02/1905Z, and ended at 03/1720Z. The polar cap absorption event remains in progress. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels. D. Stratwarm: None E.
