摘要: Abstract In this paper the results of OH (8,3) emission intensity and rotational temperature measurements made in Brazilian sector (23°S) from 1972 to 1974 are presented. Diurnal variations both parameters found fall into distinct classes, showing significant seasonal effects. A correlative study with OI 5577 measured simultaneously is also It shown that phase amplitude major part mean nocturnal two emissions can be explained by density perturbations caused solar semidiurnal tide. The increase slightly during magnetic disturbances.
