Abstract : The density of the upper atmosphere at heights between 1080 and 1170 km is evaluated from the change in the orbital period of Echo 2 for dates between February 1964 and December 1965. The air density shows a pronounced semiannual variation, while the variation between day and night is unlikely to exceed a factor of 2. (Author)
