The time delay between the peak of a geomagnetic storm and the corresponding maximum in atmospheric density was derived from precision drag data with a time resolution of 0.1 day. The mean delay time determined from about 100 events is 5.2 ± 0.4 h. This result is valid for the near-equatorial atmosphere in the height band from 300 to 770 km during the years 1961 to 1963. The amplitude of the variation in atmospheric temperature was studied as a function of the intensity of the geomagnetic storm. The temperature increase AT (degK) during a geomagnetic disturbance of intensity kp„is given by A T _ ^ + 0.03 exp (jy This paper is being issued as Mitteilung der Astronomischen Institute Bonn nr. 82.
