Abstract :
[en] The results are presented of photographic observations of asteroid positions made in August 1976 at La Silla, Chile. The quality of the sky characteristics made it possible to record objects with the magnitude 17. Measurements of all plates were conducted with the aid of the Ascorecord measuring machine of the Royal Belgian Observatory. The reduction method employed is based on the use of five reference stars. The equatorial planet coordinates can be easily obtained from the employed parameters with the aid of the formulas considered by Smart (1944). In the evaluation procedures use was made of the SAO catalog which had been recorded on magnetic tape by the Strasbourg Observatory. Three new asteroids were discovered. The obtained data are presented in two tables.
