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