The altitude distribution of the oxygen infrared atmospheric bands at 1.27 microns was measured during the total solar eclipse of 26 February 1979. The ozone concentration profile has been derived from these airglow measurements and indicates that at 85 km the concentration at totality was 7 x 1.7/cu cm, with no well defined upper layer. This reduced concentration, which is typical of summertime conditions, was probably due to perturbations in the mesospheric chemistry and transport induced by a winter warning event that was in progress at the time of the eclipse. At 60 km the ozone concentration, 2.7 x 10 to the 10th/cu cm, was enhanced above that normally measured. This increase may also have been caused by the stratospheric warming event but the effects of a particle precipitation event, which was also in progress during the eclipse, may be important.
