Abstract
We have photometrically observed HD 112859, HD 144110, and HD 208472 using the 48-cm Cassegrain reflector with an SSP-5 photometer of Ege University Observatory during the 19961997 observing seasons. Observations were made between June 1996 and March 1997 using B, V, and R filters and light curves with color variations were obtained. The amplitudes of the light variations have been estimated as approximately 0.05, 0.06, and 0.20 magnitude for HD 144110, HD 112859, and HD 208472, respectively, but considerable scattering is seen among all the phases.
