Existence of the Bands 2963, 2977 in Night Sky Spectra


THE list of wave-lengths in the light of the night sky, which was reported by Gauzit1 two years ago, includes the two second positive bands of nitrogen 2963 and 2977 with an intensity ratio of 2 to 1. Since those bands lie in the region of the great Hartley absorption band of ozone, the reality of those observations could readily be open to question. The importance of additional evidence concerning this problem is understood when it is pointed out that the shortest auroral radiation which has been reported is the second positive band at 3110.
