Absolute photometry of small main-belt asteroids in 2007–2009

We present the results of absolute photometry – the absolute brightness HV, the effective diameter, (B)VR color indices, composite light curves, period of rotation and amplitude of variations – of several small asteroids in the inner main-belt: 1344 Caubeta, 1401 Lavonne, 2947 Kippenhahn, 3913 Chemin, 3956 Caspar, 4375 Kiyomori, 4555 1987 QL, 5484 Inoda, 5985 1942 RJ, 6949 Zissell and main-belt asteroid 6867 Kuwano. The photometric observations of these objects were made in the period 2007–2009 as part of a project of photometric studies of small main-belt asteroids that involves a collaboration of a number of asteroid photometrists around the world. ► We present the results of a part of a project of photometric studies of small asteroids in the inner main-belt. ► We measured the absolute brightness, the color indices and determined the diameters of the asteroids. ► Composite light curves were constructed and periods of rotation and amplitude of variations were defined. ► It was found that the absolute magnitude of observed asteroids was mostly greater than predicted.
