B. Proton Events
The greater than 10 MeV proton flux at geosynchronous orbit exceeded the 10 pfu threshold at 17/1715Z, reached a maximum of 136 pfu at 18/0600Z, and is still ongoing at the time of this report.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to unsettled levels. Two active periods were observed at the Boulder magnetometer, and isolated active and minor storm periods were observed at high latitudes.
