Abstract:
    The present study is an analysis of V-band CCD observations of new W
    UMa contact binary OQ Dra. To carry out the analysis, Primary and
    secondary minimum were obtained and new epoch was calculated. The
    computed period of system was 0.33967 day. Light curve analysis was
    performed using Binary Maker 3 and PHOEBE that uses the latest
    Wilson-Devinney code. We obtained photometric mass ratio of
    q_ptm_=0.55.

    O'Connell effect also was seen in the fitted model. Finally, the
    best model was achieved by introducing 2 spots on each component.

Description:
    The photometric observations were performed over 5 nights between 21
    June 2015 and 14 July 2015 at RIAAM observatory (research institute
    for astronomy and astrophysics of maragha).
