Abstract

When observing the transiting extrasolar planets, we discovered a new WUMa type binary GSC 03553-00845. Following observation was carried out using the 1 m telescope at Weihai Observatory of Shandong University. Complete BVR light curves were determined. Using the W-D program, we analyzed the light curves. Photometric solution reveals that GSC 03553-00845 is a W-subtype WUMa type binary with a mass ratio of q = 2.904, it is an overcontact binary system by a contact degree of f = 29.5% with a small temperature difference between the components (Delta T = 206 K) indicating a good thermal contact between the components. More observation of GSC 03553-00845 is needed in order to analyzed the light curve variation and orbital period change.
