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. Periods of southward Bz near - 8 nT produced major and minor storm periods early in the day. Solar wind speed increased from 600 km/s to near 800 km/s at 0600 Z and has remained elevated. D. Stratwarm: None E.
