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 active. A high speed coronal hole stream became geoeffective late in the period. Solar wind speed increased from near 450 km/s to approximately 600 km/s. D. Stratwarm: None E.
