Abstract : The night airglow photographs taken by Gordon Cooper during his orbital flight of May 15 and 16, 1963, are discussed. They show an airglow layer 24=3 km thick and varying in height above the earth from 77 to 110 km. The measu9ed brightness indicates a surface brightness in a vertical column through the airglow layer 0.4 Rayleigh/A in the vicinity of 5400 A and 0.6 Rayleigh/A at 4200 A. (Author)
