Davis et al. (1982) presented a high-resolution 2.1-2.7 micron spectrum of Orion Peak 1. The spectrum shows a number of prominent H2 lines in the 1-0 S and Q branches, including Q(1)-Q(5) and Q(7). However, the Q(6) line at 4039.5 per cm is absent. Judging from the intensities of the other Q branch lines, the Q(6) line would be expected to have a flux approximately 15 per cent that of the S(1) line and thus be present at 3-4 times the noise level of the Davis et al. spectrum. In connection with the present investigation, observations are reported which were made on the nights of 1982 November 9-10. A 3.8-m infrared telescope, a Fabry-Perot interferometer, and a cooled grating spectrometer were used in the observations. Attention is given to a graph which shows the spectrum of Peak 1 obtained on November 10 divided by that of Beta Orionis, whose spectrum is also shown. A strong Q(6) line is present on a weak continuum.
