A strong emission feature at 2150 Å has been observed by a rocket‐borne spectrophotometer in an IBC II + aurora. This feature, commonly identified with the NO γ(1,0) band, is comparable in intensity to the nearby N 2 Vegard‐Kaplan bands. Comparison of the observed spectra with a theoretically produced synthetic spectrum allows all but this feature to be assigned to N 2 transitions. No bands of the v′=0 or 2 progressions or any other bands from v′=1 appear, casting serious doubt on the identification of this feature as the NO γ(1,0) band.
