Abstract

We have photometrically observed HD 82443 and HD 29697 (= V834 Tau) using the 48-cm Cassegrain reflector with an SSP-5 photometer of Ege University Observatory during the 1996-1997 observing seasons. The observations were made between November 1996 and March 1997 in B, V, and R filters, and the light curves with color variations were obtained. The amplitudes of the light variations have been approximately estimated as 0.05 and 0.1 magnitude for HD 82443 and HD 29697, respectively, but considerable scattering is seen among all the phases.
