利用天文TD-1A卫星在1973-1974年冬季对2796-2803-A双星赤道气辉的高度分布进行了四次偶然测量。观测结果表明，在非洲部分的黄昏F区，存在一层层的镁离子。水平柱密度达8×109 mg~+离子/cm~2，峰高230~480公里。三次观测到了尺度高度约为5公里的陡峭的顶部坡度。
Four occasional measurements of the altitude distribution of the 2796–2803-A doublet equatorial airglow have been made with the astronomical TD-1A satellite during winter 1973–1974. The observations indicate the presence of layers of Mg+ ions in the evening twilight F region in the African sector. Horizontal column densities reaching 8 × 109 Mg+ ions/cm² are observed with peak altitudes varying from 230 to 480 km. Steep topside gradients with scale heights of about 5 km are observed on three occasions.
