Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1130 1130 1130 120 1350 1354 1356 0570 C1.0 5300 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to active. The high speed coronal hole stream that produced several minor storm periods in recent days is now subsiding. Solar wind speed decreased to below 500 km/s by the end of the period. D. Stratwarm: None E.
