Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1243 1249 1251 0424 S16E33 M1.7 Sn 40 II B. Proton Events: None. C. Geomagnetic Activity Summary: Geomagnetic activity has been quiet to active. Solar wind speeds have steadily decreased through the period, as a coronal hole has rotated out of geoeffective position. D. Stratwarm: None. E.
