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 at unsettled to active conditions. The solar wind speed has shown a slow, yet steady decrease during the interval as a favorably positioned coronal hole enters into its waning stage. The greater than 2 MeV electron fluxes at geosynchronous orbit have again exceeded high levels. D. Stratwarm: None E.
