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