Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0740 0741 0741 260 0807 0807 0807 130 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. Solar wind speed is in gradual decline as the associated coronal hole moves out of a geoeffective position. Solar wind speed declined from almost 700 km/s to near 600 km/s over the past 24 hours. D. Stratwarm: None E.
