Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled during the past 24 hours. The greater than 2 MeV electron fluxes declined from high levels at 21/2325 UTC and remained below this threshold for the remainder of the period. D. Stratwarm: None E.
