An attempt was made to determine the dependence of meteor height on solar activity. Photographic observations of meteors were made at Ashkhabad. In order to eliminate the effect of seasonal fluctuations of the isobaric surfaces, meteors observed in August over a number of years 1955-1958 were selected. Wolf sunspot numbers for the day preceding nighttime observations served as an index of solar activity. All meteors were divided into two groups, those with a Wolf number w 100 and those with a Wolf number w 150 none were observed in the interval 100-150. For heights of maximum light the dependences were obtained by the method of least squares. According to these data meteor heights decrease with an increase in solar activity.
