초록

Surface activity of the late-type supergiant component of $\zeta$ Aurtype eclipsing binary 32 Cyg has been searched in R and I passbands for 53 nights in the 1991 season. Atmospheric extinctions in these wavelength regions are made and a linear relation between the two coefficients has been found. All the data are standardized and determined the magnitudes and colors of 32 Cyg. R, I and color curves of 32 Cyg at the outside eclipse phase are presented.
