Distortions in the radiation cavity as measured by an 1100-kilometer polar orbiting satellite

Using data from the polar orbiting satellite 1963 38C we have studied distortions in the radiation cavity and their relation to a model of the distorted magnetosphere. The study is concerned with trapped electrons of energy ≥280 kev during the period October 2 to November 5, 1963. Diurnal effects, taking into account the varying dipole orientation, in the trapped electron intensities are obtained for periods of slight, moderate, and intense magnetic activity. Consistency of the data with adiabatic invariant and energy conservation in a distorted field is suggested.
