The nightglow OH(9, 4) and O2 atmospheric (0,1) band\udemission intensities and their rotational temperatures T(OH) and T(O2),\udrespectively, observed at Cachoeira Paulista (23°S, 45°W),\udBrazil, during the period from October 1989 to December 1990, have been analyzed\udto study the nighttime mesospheric energy loss rates through the radiations from\udthe vibrationally excited OH* and electronically excited O2*\udbands. The total emission rates of the OH Meinel bands, O2\udatmospheric (0,0) and O2 infrared atmospheric (1Δg)\udbands were calculated using reported data for the relative band intensities I(&#x03BD;'',&#x03BD;')/I(9,4), IO2A(0,0)/IO2A(0,1)\udand IO2(1Δg)/IO2A(0,1).\udIt was found that there is a minimum in equivalent energy loss rate by the OH*\udMeinel bands during December/January (equivalent energy loss rate of 0.39K/day*,\udwhere day* means averaged over the night) and maximum in\udequivalent energy loss rate during September (equivalent energy loss rate of\ud0.98K/day*). Energy loss rate by the O2*\udradiation, on the other hand, is weaker than that by the OH*\udMeinel bands, showing equivalent energy loss rates of 0.12K/day*\udand 0.22K/day* during January and September, respectively
