This investigation examined the relationship between energetic electrons (1.2-16 MeV) at geosynchronous orbit and solar wind speed and Interplanetary Magnetic Field (IMF) effects. Electron flux data for a three year period, June 1979 to April 1982, came from DOD spacecraft 1979-053 in geosynchronous orbit. This data was compared statistically with solar wind and IMF data measured by other spacecraft located in the solar wind. Statistical techniques employed included graphical plotting, descriptive statistics, correlation analysis, analysis of variance, and discriminant analysis. Results from this study used daily average values and indicate clear differences in behavior between 1.2 to 6.6 MeV electrons and 6.6 to 16 MeV electrons. Electron flux in the energy ranges of 1.2-1.8 MeV, 3.4-4.9 MeV, and 4.9-6.6 MeV showed generally strong correlation with each other. Electron flux in the energy ranges of 6.6-9.7 MeV and 9.7-16 MeV also showed strong correlation with each other, but not to the three lower energy channels.
