New rocket data on auroral electron energy spectra are presented. Two regions of the aurora are sharply defined: the peak energy region, called the beam, and a strongly altitude-dependent tail of slowed-down secondary and backscattered electrons. It is shown that the oscillating two-stream instability described by Papadopoulos and Coffey (1974) accounts for the observed features of the tail.

A report is presented of detailed observations of electrons ranging in energy from 50 to 1000 keV in a relativistic electron precipitation event. The results shown were obtained with the aid of a sounding rocket that was launched at the Andoya rocket range in northern Norway in May 31, 1972. A graph is provided with the differential energy spectrum at a pitch angle of 30 deg for maximum and minimum values.-
