Photometric Observations of the Contact Binary System V523 Cassiopeiae

A total of 583 observations (193 in Δb, 190 in Δv, 200 in Δr) for V523 Cas was made on 9 nights from September to December in 2008 using the 100 cm telescope with 2K CCD camera of the Chungbuk National University Observatory. With our data BVR light curves were constructed and 9 times of minimum light were determined. We also obtained physical parameters of the V523 Cas system by analysis of the BVR light curves using the Wilson-Devinney code
