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. Isolated active periods were observed at mid latitudes between 0600 to 0900 UTC, and high latitudes between 0300 to 0900 UTC. Solar wind speed has declined from 600 km/s to 500 km/s during this reporting period. D. Stratwarm: None. E.
