Abstract:
    After 33 years of extensive studies of SS 433, we have learnt much
    about this unique system with moving emission lines in the spectrum.
    The orbital inclination is known from spectroscopic observations of
    moving lines; the distance is derived from radio interferometry of
    relativistic jets; the mass ratio of its components is determined from
    X-ray observations of jets' eclipses. In 2005, the accretion donor was
    detected as an A4-A8 giant, and its contribution to eclipse light was
    measured spectroscopically. In the present paper, the A-type star was
    detected via multicolor photometry on the basis of its Balmer jump. A
    method is proposed to estimate the interstellar reddening, able to
    measure the individual law of interstellar absorption for SS 433 from
    spectrophotometry.
