Abstract
In this article, the new light curve of W UMa type eclipsing binary star BX Peg is presented. The observations were made at the University of Kashan Observatory by DSLR camera method in Clear filter. The new light curve, times of minima and period were calculated, and finally, the O-C diagram was drawn by previous information and the new calculation in this project.
