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. Solar wind speed increased gradually from 330 km/s to near 550 km/s by the end of the period. This increase is associated with a high speed coronal hole stream. D. Stratwarm: Not Available E.
