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 active to major storm levels from yesterday through 10/1600 UTC. Since then conditions have been predominately unsettled. The high speed solar wind continues, but has lessened from the 750-900 km/s of yesterday to a steady 620 km/s. The greater than 2 MeV electron fluxes continue to be at high levels. D. Stratwarm: None E.
