Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0511 0518 0522 2420 N08E79 C8.8 Sn 1000 140 1438 1438 1439 310 B. Proton Events: The greater than 10 MeV proton flux almost completely recovered to background levels from a 3pfu enhancement on 20 Sep, following the west limb CME associated with the M2 flare from Region 2420. C. Geomagnetic Activity Summary: The geomagnetic field began at a pair of periods with unsettled levels, before decreasing to quiet conditions for the remainder of the day. D. Stratwarm: Not Available E.
