Abstract: We observed the active binary XY UMa by using 40cm telescope and CCD camera of Canakkale Observatory, 1m telescope and CCD camera of Yunnan Observatory in 2004 and 2005. The obtained BVRI photometric light curves are analyzed by means of Wilson-Devinney code, and the starspot parameters are derived for the system. The results demonstrate that the main spots are located in the medium latitude regions during our observing runs. Finally, we have discussed the spot evolution from 2004 to 2005.
