Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1831 1839 1846 0318 S13W21 C8.2 1f 170 25 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to minor storm levels. A pronounced transient flow with sustained periods of southward Bz in the interplanetary magnetic field, produced the disturbed periods. Solar wind speed decreased to less than 400 km/s by end of period, but continued southward Bz is prolonging the disturbance. D. Stratwarm: None E.
