The first photometric study of W UMa eclipsing binary OQ Dra

•A ccd photometry study of W UMa contact binary OQ Dra is presented.•Data reduction and aperture photometry were done in IRAF.•Parameters of the system achieved by light curve modelling with PHOEBE (W-D code).•Unspotted and spotted models has been introduce.•Period=0.33967, Mass ratio=0.55, i=73 and spectral type of K achieved for OQ Dra.

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 qptm = 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.
