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.
