Abstract

Thee seasonal variations of intensities of atomic sodium, vertical distribution, seasonal variations of the ratio Na components and the height of the emission layer are obtained on the basis of spectrographic observations in 1961—63. One must pay attention to the result, that the observations carried out in two directions (in the Sun's vertical. h=25° and in the direction of North, h=23 ) displayed different seasonal variations; the intensity maximum observed in the Sun's vertical in winter is shifted to the North in March-April. It is suggested that maximum of intensity is shifted vertically in dependence on the season of the year. The sharply expressed effect of morning and evening in the correction of North is also observed.
