We report the results of observations of Be/X-ray binary system 1H1936+541. All the data were obtained on the base of Lisnyky observational station of AO KNU and Southern Station of the Sternberg Astronomical Institute MSU with the help of three different CCDs in U, B, V, R, I filters from 2008 till 2014. During this time photometrical variability were occured in all bands but the most significant changes are present in U and I bands. Variability in these bands anticorrelates with each other and are in good agrement with the model of decretion disk around Be star. So, photometrical variability indicates about changes in decretion disk structure. Further photometrical and spectral observations will help us to creat a real model of this system.
