The upper-mesosphere airglow emissions O I 5577, NaD and OH have been observed at Cachoeira Paulista (22.7 deg S; 45.0 deg W) Brazil. Nocturnal variations, their seasonal dependencies in amplitude and phase, and annual variations of these emissions are presented, analyzing the data obtained from 1977 to 1982 during the ascending phase of the last solar cycle. The nocturnal variations of the O I 5577 emission and the OH rotational temperature showed a significant semidiurnal oscillation, with the phase of maximum moving from midnight in January to early morning in June. Semiannual variation of the O I 5577 and NaD emissions with maximum intensities in April/May and October/November were observed. The OH rotational temperature, however, showed an annual variation, maximum in summer and minimum in winter, while no significant seasonal variation was found in the OH emission intensities. Long-term intensity variations with the solar sunspot numbers and the 10.7-cm flux are also presented.
