A preliminary compilation of DS-programme star positions
A catalog is presented of the double-star-program (DS-program) starpositions, listing right ascensions for 930 DSs and declinations for1225 DSs of the program. The positions were compiled from the observedvalues obtained between 1980 and 1987 with the meridian circles of sixUSSR observatories (the Moscow, Kazan', Kiev, Khar'kov, Odessa, andTashkent Observatories) and the Belgrade Observatory. The measurementsand the treatment of the observational material were performed using therelative method, and the FK-4 system stars were used as reference stars.

Photographic measures of visual binaries
A total of 152 photographic measures of selected visual binaries,carried on with the astronometric reflector of the Observatory ofTorino, are given (5th series). The measures are the result of acritical selection among the observations, rejecting those havingdeviations from the mean larger than 3 sigma = 80 marcsec.
