B. Proton Events
The greater than 10 MeV proton flux at geosynchronous orbit reached the 10 pfu event threshold at 11/1055Z, and the 100 pfu event threshold at 11/1630Z, reaching a peak value of 114 pfu at 11/1645Z. The greater than 10 MeV proton event is still in progress. The greater than 100 MeV proton flux at geosynchronous orbit reached the 1 pfu event threshold at 11/0940Z with a peak value of 2 pfu at 11/1400Z, and ended at 11/1955Z.
