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 quiet to major storm conditions. Major storm periods were observed between 28/0000 to 0300 UTC and 28/0300 to 0600 UTC. Heightened activity was due to the onset of a coronal hole high speed stream. Solar wind speed at ACE increased early in the period from approximately 540 km/s to a maximum of 710 km/s around 28/0400 UTC. Wind speed has been slowly declining and ended the summary period near 550 km/s. D. Stratwarm: Not Available E.
