Abstract
We present results of our CCD photometry of near-Earth asteroids (1627 ), (4957), (6569), 1993 UC, 1994 AH(2), 1994 CB, and 1994 LX, that we made in 1994 and 1995. Synodic rotation periods were determined for 6 of them for the first time, and we provide constraints and show a cons istency of our results with the earlier spin vector determination for (1627). Among the other objects, the most interesting observations wer e obtained for (4957), containing information useful for future spin v ector determinations; 1993 UC, that is the second fastest rotator know n among asteroids (period 2.340 hr); 1994 AH(2), an object on the marg in between asteroidal and cometary orbital types, with the probable ro tation period of 23.95 hr; and 1994 CB, one of the smallest (est. 0.2 km) asteroids observed photometrically up to now.
