We used a photoelectric photometer designed by V.M. Lyutyi and the Zeiss-600 telescope of the Sternberg Astronomical Institute’s Crimean Observatory to acquire precise UBV brightness measurements (σ obs V ˜ 0.007m) for the eclipsing binary system HS Her in 1984 1991. These measurements continue the homogeneous series of observations of this star commenced in 1969 by D.Ya. Martynov using the same equipment. Our detailed analysis of this homogeneous 22-year series of photoelectric observations has yielded a self-consistent set of physical and geometric parameters of the binary, and enabled us to establish the evolutionary stages of its components. The systems’s primary, M 1 = 5 M &sun;, is at the beginning of its main-sequence evolution, whereas its secondary, M 2 = 1.6 M &sun;, has not yet reached the main sequence. The binary’s age is estimated to be t = (17 ± 3) × 106 years.
