Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0237 0241 0245 0486 S19W89 M1.6 Sf 1046 1052 1056 0486 S16W90 M5.3 Sf B. Proton Events: A greater than 10 MeV proton event from the X28 flare began at 04/2225Z, reached a peak value of 353 pfu at 05/0600Z, and is currently in progress, but declining. A greater than 100 MeV proton event began at 05/0535Z, reached a peak value of 1.3 pfu at 05/0540Z, and ended at 05/0705Z. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels. D. Stratwarm: None E.

Comments: The GOES EPS instrument for greater than 2 MeV electron measurement at geosynchronous orbit is exhibiting proton contamination at this time, making the 2 MeV electron fluence data unreliable.
