OBSERVATIONS OF THE OH AIRGLOW EMISSION

The OH airglow emission in the J and H bands was observed for the purp ose of determining the linewidths, the precise wavelengths of individu al lines, and also the continuum emission level between lines. The lin es were not resolved with a resolving power of about 17,000. Wavelengt hs and intensities were measured for approximately 120 lines from 1.1 to 1.8 mum. The continuum emission intensity was also measured on a da rk night and was as low as 590 photons s-1 m-2 arcsec-2 mum-1 at 1.665 mum. The level is about one-fiftieth the average flux of the OH airgl ow emission in the H band.
