The first high-accuracy CCD UBVRI light curves for the recently discovered eclipsing system V839 Cep (P = 9d.96,V=9m.85, Sp B5) were obtained. A photometric solution of the light curves and physical characteristics of the component stars are derived. The apsidal motion in the system is detected. The eclipsing star is the component A of the visual binary GSC 3964 0741, ∆ Mag = 1.1, Sep.=0”.2 and situated in field of galactic open cluster Trumpler 37.
