We present the photometric solutions of the variable star V30We follow the Jahn et al. (1995) nomenclature for variable names. that is in the foreground of intermediate open cluster NGC 7789. The observations were done in the V passband using the 2 m telescope at the IUCAA-Girawali Observatory in India. The analysis is done using the Wilson-Devinney Code (2003) and the fitted light curve is presented. The photometric solutions reveal a W-subtype contact configuration. The photometric mass ratio is found to be 0.395 and the absolute masses and radii for the components are deduced as 1.25 Ms and 0.97 Rs for the primary and 0.49 Ms and 0.93 Rs for the secondary, respectively. No signature of third light is found in the system.
