A short survey of the climatic and physico-geographic characteristics as well as of conditions of astronomical seeing (star images) at Abastumani is given. Abastumani is situated at 41°43' latitude and 42°45' E longitude from Greenwich at approximately 1500 m above sea level. The Abastumani district, occupying a mountain valey of roughly 50 square kilometers, is bounded in the North by the Adjar-Imeretian Mountains reaching a height of 2160-2460 m; in the West and the East by the spurs of this mountain range 1800-2100 m high from the valey's border, while in the South it ends in the so-called Akhaltsikhe mountain plain, of 1200 m altitude. The mountains, surrounding the Abastumani valey in the West and the East are covered with thick pine-woods. The upper parts of the Northern mountain range are occupied with pastures of rich, soft grass. Abastumani is a mountain-resort, the excellent climatotheurapic properties of which are well known. To characterize Abastumani's climate, the mean values of various meteorological factors reduced on the basis of approximately 35 years of observations are given in this paper. Table I lists the mean temperature, the mean maximum and minimum for the different months of the year. Cloudiness and the number of totally or partially clear days are indicated in Table II. Table III shows the distribution of the number of clear and partially clear days and nights during the last four years. Table IV gives the velocity of wind. The transparency of the air is characterized by Table V. The transparency coefficient of the atmosphere determined photographically equals 0.808. The visual determination of the coefficient led to the value equal to 0.878. Table VI lists the values of the turbidity factor calculated on the basis of 1934 observational material for a solar latitude of 30° (mass=1.7). Table VII shows the star images according to the Pickering Scale. The oscillation of star images is shown in Table VIII. Fig.1 gives the curves of star images obtained by Pickering's method. July, 1937
