Rotation Periods for Small Main-Belt Asteroids From CCD Photometry
Abstract
We report the results of new photometric observations of 19 main-belt asteroids, most of them of small size, i.e., D<~50 km. The observations were carried out at the Observatório do Pico dos Dias (Brazil) and at the Estación Astrofísica de Bosque Alegre (Argentina), providing more than 50 single- night light curves. The obtained rotation periods, ranging from 3.2 to 11.5 hr, are presented along with the corresponding composite light curves. Observations carried out at the Observatório do Pico dos Dias, operated by the Laboratório Nacional de Astrofísica (Brazil), and at the Estación Astrofísica de Bosque Alegre (Argentina).
