Phys. Rev. 38, 1048–1051 (1931)The Light of the Night SkyReceived 1 June 1931; published in the issue dated September 1931 The two lines at 4416A and 4168A, recently reported by Lord Rayleigh in the light of a very bright night sky, are identified as OII lines. A theory is proposed which accounts for the strong excitation of the green aurora line both in the night sky and in the aurora borealis. The theory explains why no O2+ bands are found in the aurora while N2+ bands are very strong. Explanations are proposed for the two lines of singly-ionized oxygen and for the continuous spectrum in the night sky. Experiments performed by the writer substantiate the theory. © 1931 The American Physical Society URL:
