Abstract
The eclipsing binary system which is catalogued in MACHO as 47.2135.29 is analyzed in detail for orbital elements and absolute parameters based on the MACHO observations and the latest values for the distance modulus of LMC. The period of the system is found more accurately, by minimizing the dispersion in the folded light curves. The binary is found to be a young semi-detached binary and is potentially a beta Lyrae system.
