B. Proton Events
The greater than 10 MeV proton flux at geosynchronous orbit reached the greater than 10 pfu threshold at 20/0850Z, reached a peak of 22 pfu at 20/0925Z, and dropped below the S1 event threshold at 20/1125Z. This proton event was associated with the M3/Sn at 20/0756Z from Region 1976.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to major storm levels.
