The emission of both 5893 A and 3303 A has been observed from a sodium cloud in the upper atmosphere. The yellow line is at least 100 times more intense than the ultraviolet line. The appearance of the 3303 A line with the observed intensity proves conclusively that the sodium twilight flash results from resonance scattering.
