Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: The greater than 10 MeV Proton Flux was above the 10 PFU threshold for the entire period. The event began at 26/1125Z and reached a maximum value of 80.3 PFUs at 27/0125Z. The event was associated with a long duration C1 flare at 26/0710Z in conjunction with an eruptive filament channel near Region 1353 (N08W49 at time of event). C. Geomagnetic Activity Summary: The geomagnetic field was mostly quiet. D. Stratwarm: Not Available E.
