Proton Events: The greater than 10 MeV proton event that began on 01 October continued. The (preliminary) maximum flux for this event was 2360 pfu at 02/0810 UTC. The greater than 10 MeV proton flux was 131 pfu at the close of the period and was gradually decreasing. C. Geomagnetic Activity Summary: Field activity ranged from unsettled to major storm levels. Major storm levels occurred during 02/0600 - 0900 UTC. D. Stratwarm: None E.
