Proton Events: The greater than 10 MeV proton flux reasched S2 (Moderate) levels, with a peak value of 125 pfu at 22/0355 UTC, and decreased below the S1 (Minor) threshold at 22/1845 UTC. The greater than 100 MeV proton flux reached a peak value of 7 pfu at 21/2010 UTC, but have since decreased well below the 1 pfu SWPC warning threshold. C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled. D. Stratwarm: Not Available E.
