Statistical Analysis of Energetic Electrons (3.4-16 MeV) at Geosynchronous Altitude and Their Relationship to Interplanetary Parameters.
Abstract
This analysis attempted to examine the relationship between energetic electrons in the magnetosphere between the energy levels of 3.4-16 MeV, solar wind speed, and the Bz component of the Interplanetary Magnetic Field (IMF). The statistical analysis was accomplished using the SPSS computerized package and data from DOD spacecraft 1979-053 at geosynchronous altitude. The electron flux data from this satellite was compared statistically with IMF and solar sind plasma data measured by other spacecraft located in the solar wind stream. Analytic techniques used included graphical plotting, descriptive statistics, scatter plots, correlation analysis, and analysis of variance (ANOVA) tests. This statistical analysis of energetic electrons at geosynchronous altitude and their relationship to solar wind speed and the IMF Bz component resulted in different findings for electron flux above and below approximately 6.6 MeV energy level. There was a weak, positive correlation between electron flux in the energy ranges 3.4 - 4.9 and 4.9 - 6.6 MeV and values of solar wind speed, after two days passage.
