The results of new CCD observations are presented as part of the campaign we are performing in Brazil to measure rotational periods for small asteroids. The observations presented here have been acquired at the Pico dos Dias Observatory between 1997 and 2002 and result in 48 single night lightcurves for 20 asteroids, most of them Main-Belt objects with D < 40 km. We present the rotation periods – ranging from about 3 to 18 hr – along with the composite lightcurve obtained for each observed object.
Key words: minor planets, asteroids / solar system: general
