Preliminary data on variations of OH airglow during the Leonid 1999 meteorstorm

As part of the 1999 Leonid MAC Campaign an extensive set of infrared (1.00 - 1.65 mum) airglow spectra and imaging data were collected from onboard th e USAF FISTA aircraft. These data will permit a detailed study of the upper atmospheric conditions over a several day period centered on the Leonid me teor storm of 17/18 November, 1999 as well as during the meteor storm itsel f. We describe initial results of a spectral analysis that indicates a smal l but significant enhancement in the OH airglow emission during the peak of the storm but we cannot yet be certain of a cause and effect relationship. No similar systematic enhancement was observed in the O-2 (1.27 mum) airgl ow emission recorded with the same instrument.
