Proton Events: The greater than 10 MeV protons were elevated above background following the X3.3 flare on 24 Oct and were further elevated due to contirbutions from the X1.8 on 26 Oct. C. Geomagnetic Activity Summary: The geomagnetic field reached minor storm levels due to arrival of a CME that left the Sun on 24 Oct. D. Stratwarm: Not Available E.
