Scientific paper

Narrow-band photon-counting photometry of the binary system SS 433 (V1343 Aquilae) in the stationary H-alpha emission line and in the adjacent continuum was carried out in 1981-1982 at different orbital phases phi and precession phases psi. The H-alpha intensity varies by a factor 2.4 over the 13-day orbital cycle, reaching minimum at phi = 0.0-0.1, when the normal star eclipses the accretion disk. Hence, most of the stationary H-alpha emission originates inside the binary system, presumably within the accretion disk. The mean stationary H-alpha intensity varies with psi.
