Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1335 1336 1337 180 1841 1841 1842 140 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to minor storm levels with major storm conditions at high latitudes. Storming conditions are the result of the passage of a magnetic cloud. Data from the ACE spacecraft showed a smooth rotation of Bz to strong negative values starting at approximately 04/0000Z. The Bz remained negative for the rest of the day. D. Stratwarm: None E.
