The GO Cygni system is a short period -0.7177 days- eclipsing binary with a βLyrae-type light curve. In this study our new BV photoelectric observations of the system, made at the Bucharest Observatory during 1993-94 are presented. These, and our old ones -made at the Kryonerion Astronomical Station of the National Observatory of Athens, Greece, in 1985- are analysed using Wood's program. The geometrical elements of the system -derived from the present analysis- correspond to a contact configuration suggesting that it belongs to the so-called near contact binaries. Moreover, its physical parameters lead to an unevolved system with both of its components located very close to the ZAMS. Finally, its orbital period is examined and found to show continuous increased.
