Abstract:

An array of sensitive electrostatic analyzers was launched on the satellite INJUN 5 into a nearly polar, low-altitude orbit. A series of three traversals of the northern auroral zone in the local evening sector on 3 December 1968 has provided high energy- and time-resolution observations of low-energy proton and electron intensities within the energy range 50 or E or 15,000 eV before, during and after a polar magnetic substorm. The region of high intensities of plasma-sheet electrons expanded dramatically during the substorm, extending about 3.5 degrees farther poleward and about 4.5 degrees farther equatorward relative to that of the preceding pass.
