New BVR light curves of the eclipsing binary system NSV 5904 have been constructed based on CCD observations obtained using 1.88-m telescope Kottamia observatory during phase testing and adjusting its optical quality May, 2009. times minima epoch determined from these curves. Using Binary Maker 3.0 (BM3) package, a preliminary determination photometric orbital physical parameters are given.
