- Аннотация: The eclipses of the primary component by the secondary one in DQ Herculis (N Her 1934) were analyzed by the light curves obtained by photometric observations in 1982 - 1986. It is suspected that the value O-C varies with time by the sinusoidal law with a period of about five years. Even being confirmed by further observations, any hypothesis - either the presence of the third component in the system, or the rotation of apsid line - seems inadequate to explain the phenomenon because the secondary minimum is not to be seen on the UBVRI light curve.
