Abstract
We report the discovery of two eclipsing binaries in the young open cl uster NGC 654, based on 17 nights of CCD observations in Ostrowik obse rving station. Their light curves are characteristic for detached syst em, probably with spots on the surface of the brighter component, and with synchronized rotation.
