Аннотация: A new WBVR and Hα-photometry of SS433 is given. Observations were carried out with the 2-meter reflector of the Shemakha Astrophysical Observatory at the dates corresponding to the phases ψ = 0 and ψ = 0.35 of the precessional 164d-period. The ratio of depths for the primary and secondary minima in W and V on the orbital light-curves at a precessional phase ψ = 0 is such that it cannot be explained in terms of a simple geometrical model of the accretion disk eclipses. These W and V depths can be understood taking into account the "reradiation" of the accretion disk radiation by the "normal" star. The orbital light-curves obtained at ψ = 0 and ψ = 0.35 are compared with those observed by Cherepashchuk et al. (1982) at ψ = 0.5. The observational data are discussed in comparison with model simulations for SS433.
