Description
An array of sensitive electro- static analyzers, or LEPEDEA's, on the low-altitude polar-orbiting satellite INJUN 5 have yielded a large body of observations of auroral zone precipitation patterns for protons and electrons in the energy range 50 < E < 15000 eV. During relatively quiet times the charged particle intensities equatorward of the trapping boundary for electrons E > 40 kev are similar to intensities observed with similar instrumentation in the plasma sheet at large radial distances. Poleward of the trapping boundary the primary energy influx is associated with 'inverted V' electron precipitation events.
