Abstract
The new light curve and ephemeris of two eclipsing binary systems BQ Ari and V1370 Tau are presented. The observation was made with CCD through C filter, and we used the Czech astronomical society’s database to extract raw data, to obtain the time of minimums we used Table Curve software and then calculate O-C with the new ephemeris.
