Abstract :In this study, we investigated light curve analysis of contact binary system NO Vul. Also, we investigated orbital period variations of contact binaries NO Vul based on all published minima times and also those obtained from our own observations. Photometric observations are obtained from the ASAS public archive. Physical parameters of the system are derived using the modeling code by Wilson and Dewinney’s (WD). Photometric results indicate that NO Vul is q = 0.72(2) and about f =%19 respectively and the derived orbital inclination i =77(1).Keywords : Contact binary stars, light curve anaysis, orbital period analysis, NO Vul
