Abstract

We present the photometric analysis of the detached eclipsing binary V2480 Cyg. After taking the pho- tometric data, the light curve was analyzed in PHOEBE software, which uses the Wilson–Devinney code. Due to the observed O’Connell (1951) effect in light curve, we introduce a spotted model with 3 spots on the components, and the exact parameters of the system have been achieved. The main parameters of the system were calculated as about q ptm = 1.7, T eff1 = 8075 °K and T eff2 = 3829 °K.
