摘要：AbstractNew CCD observations of the W UMa type binary systems GSC 1283-53 and GSC 702-1892 have been analyzed using the Wilson–Devinney Code to determine their photometric and geometric elements. The results show that the system GSC 1283-53 may be classified as A-subtype W UMa eclipsing binary with a photometric mass ratioq=0.277, and the degree of over contactf=83.5%. While the system GSC 702-1892 is found to be a detached eclipsing binary with the photometric mass ratioq=0.49.
