The AEPI (Atmospheric Emissions Photometric Imager) experiment on the ATLAS‐1 shuttle mission (launched March 24, 1992) imaged the earth night airglow emission in the O 2 Atmospheric (0,0) bands, at 762.0 nm. Earthward views of O 2 A bands show structure from gravity waves which exhibit extended horizontal structure with horizontal wavelengths on the order of 50–100 km. These observations of the O 2 A (0,0) bands are particularly interesting since in this wavelength the lower atmosphere absorbs all the earth‐reflected emissions and most of the spectrally diffuse backgrounds. Herein we present observations of gravity waves using a topside airglow imaging technique.
