Abstract
A high-dispersion photographic infrared spectrum covering the 7300–8700 Å region was obtained from the great red aurora of February 10/11, 1958. This spectrum shows the λλ7774 and 8446 OI lines to have been enhanced at least five times relative to normal aurora. The most striking feature of the spectrum was the appearance with high intensity of the forbidden 2D–2P multiplet of OII. The measured wavelengths and relative intensities of the features of the spectrum are listed.
