The changes in the orbit of the satellite Star-rad 1962 beta, kappa between January and June 1966 are analysed to determine the variation in upper-atmsophere density at a standard height 220 km a little above the satellites perigee height. It is found that the air density in May-June was about 30 greater than in January-February, as a result of the increase in solar activity. The fluctuations in density on a shorter time-scale, 2 to 3 days, are also shown. Author
