Abstract

Two colour(B & V) photoelectric observations of EB-type eclipsing binary GO Cyg were carried out for 15 nights during October and December 1996. Three new times of minimum derived from our own observations are presented. With these and previously published times, the period variation is studied, and a continuous period increase of $dP/dt{\approx}1.51{\times}10^{-7}d/yr$ is estimated from the quadratic ephemeris.
