Abstract
We report observations of airglow (OI 630 nm) intensity perturbations which are possibly caused by thermospheric gravity waves. Those perturbations are not very frequently observed during the year, as discussed below. Two photometers scanned approximately 75 degrees around zenith in the magnetic meridional and zonal p1lanes at Caçhoeira Paulista (CP, Geogr. 22 41 S, 45000 W, dip 28 S).
