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 isolated active conditions late in the period. A coronal hole high speed stream has rotated into a geoeffective position. Solar wind speed gradually increased to near 600 km/s. The IMF Bz was generally northward, but occasional brief southward excursions occurred late in the period. D. Stratwarm: Not Available E.
