The first simultaneous observations of electrostatic shocks as inferred from their low altitude extensions, electron beams, and visual auroral arcs on the same magnetic field line are presented for three events in 1977. The events are the result of a comparison of electric field and particle data from the S3-3 polar orbiting satellite with all-sky camera data from stations in Alaska and Antarctica. All of the events were at low altitude (<4000 km), showed indications of regions of parallel electric field above the satellite, and were in agreement with potential models reported by other researchers that indicate that the electrostatic shock is one of the mechanisms of auroral particle acceleration.
