Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1000 1110 1309 1314 N25W77 M1.3 Sf B. Proton Events: A greater than 10 MeV proton enhancement was observed in GOES 13 flux data associated with the long duration M1 flare at 22/1110Z from Region 1314, however the proton flux has not reached the 10 PFU threshold. C. Geomagnetic Activity Summary: The geomagnetic field was quiet. D. Stratwarm: Not Available E.
