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 minor storm conditions. Activity was due to the continued influence of a coronal hole high speed stream. Solar wind speed at ACE has decreased from approximately 680 km/s to 550 km/s. D. Stratwarm: Not Available E.
