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 quiet to active levels. Early in the period solar wind velocity increased to over 600 km/s marking the onset of the expected high speed stream. Fluctuations in the Bz component of the interplanetary magnetic field to -8 nT resulted in isolated active conditions. D. Stratwarm: None E.
