B. 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.
