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 with an isolated active period between 09/0900 - 1200Z. A sustained period of southward IMF Bz produced the active conditions. Solar wind speed declined to near 400 km/s. D. Stratwarm: Not Available E.
