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 59 pfu (S1 - Minor) observed at 27/1845Z, in response to the arrival of a CME. The 100 MeV flux enhancement at geosynchronous orbit (peak 0.9 pfu at 25/1945Z) continued to decay toward background levels. C. Geomagnetic Activity Summary: Geomagnetic field activity ranged from quiet to major storm levels. D. Stratwarm: Not Available E.
