Abstract : Under Contract AF 19(628)-5062 Geo-Science, Inc., has conducted airglow observations at Sacramento Peak, New Mexico, and research from April 1965, through September 30, 1966. Observations were made of the oxygen lines at 5577 A and 6300 A, and of the sodium doublet at 5890-96 AA with a birefringent filter photometer. The zenith values of the collected data were scaled and tabulated. Studies of the Sac Peak data showed no significant difference in the diurnal variation of zenith 5577 A for the years 1957-59 sunspot maximum and 1962, sunspot minimum. Harmonic analyses of the average monthly data from 21h-04h for the years 1957-62 were done. Diurnal variation studies were made of the zenith green line intensities for Tonantzintla, Mexico, Huancayo, Peru, and San Juan, Argentina for the years 1957-63. Studies were made of the seasonal diurnal variations for these and other worldwide stations. Some special analyses were made of the 1965 solar eclipse airglow data from Huancayo, and the variations in airglow intensities during sudden magnetic storm commencements. Considerable effort was expended upon upgrading the airglow equipment and its absolute calibration. It was demonstrated that calibrations using the moon as a source yield valid data.
