Abstract

BY means of a new spectrograph, constructed by J. Cojan at the Société Générale d'Optique, Paris, combining the high light power F : 0.65 with a fairly good dispersion, four spectrograms were taken at the Auroral Observatory, Tromsoe, on December 3, 1951, at about 23h. 00m. The spectrograms were taken on Kodak 103a-T plates and in rapid succession on the same plate with times of exposures from 4 to 10 min.
