Аннотация:The analysis of minima timings of the newly discovered W UMa variable GSC 3937 2349 (V =13.2 mag, P = 0.2875 d) revealed the light time effect that can be assigned to the third body in the system. Parameters of the third body orbit, P3=3.89 year, ecc.=0.1, were derived and its mass was estimated, which turned out to be comparable to the mass of the components of the eclipsing system.
