The New Ephemeris of BZ Leo, V2545 Cyg, and V0402 Gem

Abstract : The new ephemeris of three eclipsing binary systems BZ Leo, V2545 Cyg, and V0402 Gem are presented. The observation was made with CCD through the C filter. These three W UMa systems studied for the first time so we used the Czech astronomical society's database to extract raw data from the complete light curves, to obtain the time of minimums to calculate O-Cs with the new ephemeris.
