Electron Intensities over Auroral Arcs
This report is a summary of measurements of electron intensities made from two sounding rockets flown over auroral arcs. The main conclusion drawn from these measurements is that both the auroral arcs occurred at the boundary between two magnetospheric plasmas. This conclusion is based on the fact that some of the observed changes in electron energy spectrum are unlike the changes to be expected on grounds of continuity from a single source plasma accelerated by different degrees.
