Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1954 2010 2026 B5.1 100 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels. Two separate periods of isolated active conditions were observed due to Bz fluctuations near -10 nT. Solar wind velocity remained relatively steady between 450 - 500 km/s. D. Stratwarm: None E.
