OBSERVATIONS OF THE OH AIRGLOW EMISSION

The OH airglow emission in the J- and H-bands was observed for the purpose of determining the line widths, the precise wavelengths of individual lines, and also the continuum emission level between lines. The lines were not resolved with a resolving power of about 17000. Wavelengths and intensities were measured for approximately 120 lines from 1.1 to 1.8 microns. The continuum emission intensity was also measured on a dark night and was as low as 590 photons s-1m-2 arcsec-2 um-1 at 1.665 um. The level is about one fiftieth the average of the OH airglow emission in the H-band.
