The differential flux of secondary electrons with energy greater than 6 ev was measured in a steady IBC I + aurora with an electron spectrometer aboard an Aerobee rocket. Except for the absence of structure in the energy range 10–20 ev, the observed spectrum is in excellent agreement with a recent theoretical prediction. About one‐tenth of the observed N 2 + emission at 3914 A can be explained by secondary electron excitation.
