Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0655 0702 0707 1931 S16W23 C2.2 Sf 100 B. Proton Events: The 10MeV proton flux at geosynchronous orbit became enhanced beginning around 26/0900Z due to a far-sided coronal mass ejection first observed in STEREO-B imagery at 26/0410Z. A maximum 10MeV proton flux level of 2 pfu was observed at 26/2125Z C. Geomagnetic Activity Summary: Quiet D. Stratwarm: Not Available E.
