Venus nightglow was observed at NASA IRTF using a high-resolution long-slit spectrograph CSHELL at LT = 21:30 and 4:00 on Venus. Variations of the O 2 airglow at 1.27 lm and its rotational temperature are extracted from the observed spectra. The mean O 2 nightglow is 0.57 MR at 21:30 at 35°S-35°N, a
