Scientific paper

Photoelectric UBVRI' observations of the eclipsing binary V453 Cyg were carried out on Mt. Maidanak during 1984-1988. Fluctuations exceeding measurement errors are observed on the light curves. The photometric orbital elements were obtained by means of Lavrov's (1981) direct machine method. Absolute dimensions of the V453 Cyg components are given. The stars lie on isochrones of approximately 10-million yr on the H-R diagram, which somewhat exceeds the cluster's age. The evolution of close binary system components at an early stage may differ from the evolution of single stars of the same mass.
