Proton Events: The greater than 10 MeV event at geosynchronous orbit that began at 25/1355Z in the wake of the Feb 25 X4/2b flare continued, with a peak flux of 23 pfu (S1 - Minor) observed at 26/0010Z. Greater than 10 MeV flux levels leveled off in the high teens during the period with no significant decay evident. The X4 flare-associated greater than 100 MeV flux enhancement at geosynchronous orbit (peak 0.9 pfu at 25/1945Z) also continued and gradually decayed toward background levels. C.
