Scientific paper

The spectrum of an aurora has been obtained at moderately high resolution by using a wide-field interferometer-spectrometer. The free spectral range was from 0.83 to 1.67 micron at a midrange resolving power of about 1800. The principal auroral features observed during an IBC III(+) breakup on the night of April 19, 1974, at Chatanika, Alaska, were the N2(+) Meinel bands, the N2 first positive bands, and certain atomic O and N emission lines. Comparisons of the auroral spectra are made with both high-latitude airglow and laboratory spectra taken by the same instrument.
