Absolute intensities of the O2 (0-1) atmospheric band night airglow emission have been observed from near Longyearbyen on West Spitsbergen (78.4 deg N latitude, 15 deg E longitude, geographic) during a 2-month period around winter solstice (1982-1983). Intensities ranging from 110 R to 1590 R with a mean of 570 R + or - 60 R are observed. There is no clear maximum or minimum around solstice. A semidiurnal tide component giving rise to a 25-30 precent intensity variation of the O2 (0-1) atmospheric emission is present in the data. The maximum and minimum are found to occur at about 0400 and 1000 local time, respectively. No diurnal tide component larger than + or - 3.4 percent is present in the data. The day-to-day and short time variations both show a quasi-regular wave pattern which may be associated with gravity waves.
