Abstract Measurements of the complete pitch-angle distribution of precipitating auroral electrons in the energy range 0.5 to 25 keV in several arcs are presented. The measurements were made with a time resolution of 2s between altitudes of 400 and 700 km by electrostatic analysers carried on a sounding rocket. The angular structure and temporal development of suprathermal burst events are discussed, together with constraints on the responsible mechanism, and a possible mechanism is suggested.
