Abstract
A CCD photometric study is presented for the eclipsing binary system 2MASS J20004638+ 0547475. Observations of the system were obtained in the V, R and I colours with the 2Kx2K CCD attached to 1.88m Kottamia Optical Telescope. New times of light minimum and new ephemeris were obtained. The V, R and I light curves were analyzed using the PHOEBE 0.31 program to determine geometrical and physical parameters of the system. The results show that 2MASS J20004638+ 0547475, is A-Type WUMa and is an overcontact binary with high fill-out factor= 69%. The current evolutionary status of the system indicates that the primary component lies very close to the main sequence while the secondary is evolved. The asymmetric maxima were studied and a modeling of the hot spot parameters is given.
