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.
