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 minor storm levels. A recurrent high speed coronal hole stream and a sustained southward Bz are believed responsible for the elevated activity. The solar wind speed exceeded 800 km/s at approximately 27/0600Z D. Stratwarm: None E.
