【 摘 要 】

We present the first results of our new program aimed at relatively bright neglected (near-)contact binaries. The targets can be observed using small telescopes from several to several tens of centimeters in diameter. Light ephemeris determined by phenomenological modeling and physical parameters of the system obtained by Wilson-Devinney method are given for the first stars V373 Dra, OQ UMa from our program.
