Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0111 0111 0111 600 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. A declining high speed stream with very low density and weak northward IMF Bz continues to buffet the Earth's magnetic field. Solar wind speed declined from near 700 km/s to below 600 km/s by the end of the period. D. Stratwarm: None E.
