Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1106 1144 1231 9866 S10W58 M1.0 1f B. Proton Events: The greater than 10 MeV proton event remains in progress, with a maximum flux of 53 pfu observed at 19/0650 UTC. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to minor storm levels Minor storm levels were observed early in the day, due to a three hour period of sustained southward Bz during 0200-0500 UTC.
