Statistical results from a survey of 93 passes through the high‐latitude extension of the
plasma sheet of electron data from the Hydra instrument on the Polar spacecraft show that …

This paper presents examples of electron and proton differential energy spectra between∼
100 ev and 18 kev measured with hemispherical plate electrostatic analyzers on the Vela …

The magnetotail plasma sheet thins down and then becomes thick again at 18 RE during a
magnetospheric substorm. Thinning often starts coincident with (±1 min) substorm onset …

In this preliminary report on low‐energy (0.3 to 3 eV) secondary electrons in the auroral E
layer (90 to 150 km), we compare intensities of plasma lines observed with the Chatanika …

Three‐dimensional measurements from the ISEE 1 low energy electron spectrometer are
used to map the location of the inner edge of the plasma sheet and study the anisotropies in …

This paper reviews the principal features of the distribution of plasma in the magnetosphere
as inferred from observations of particles with energies in the keV range and below. Low …

The projection along the magnetic lines of force of the outer boundary of the plasma sheet
onto the ionosphere is shown to follow closely the poleward edge of a mass plot of auroral …

The electron velocity distribution function is presented in the energy range 25 eV< E< 15
keV during a rocket flight over an active aurora. The electron measurements are compared …

On December 5, 1983 the polar orbiting satellites NOAA‐7 and DMSP‐F6, while in opposite
hemispheres, each crossed a narrow structure of auroral electron precipitation at nearly the …

The flux of precipitating electrons in the northern auroral zone has been measured with
scintillation‐type detectors aboard a polar orbiting satellite. The total preciptated energy and …
