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 active levels due to coronal hole effects. Solar wind velocities reached peak values near 600 km/s at 07/0900 UTC and have stabilized near 550 km/s. The Bz component of the interplanetary magnetic field has been predominantly positive resulting in only isolated active conditions. D. Stratwarm: None E.
