Measurements of high altitude (<1.3 R e) ions and electrons at auroral energies are used to provide evidence of parallel electric field acceleration over the dusk to midnight auroral regions for both the north and south hemispheres. The data, taken on August 12, 1976 by charged particle spectrometers on the S3‐3 satellite, show evidence of potential differences of ∼2 kV below and ∼1 kV above a satellite altitude of 7300 km.
