Аннотация:CCD BVRI and unfiltered photometry is presented for the type IIn Supernova2016ehw. The object reached maximum with R_{max}=15.4 mag and absolute magnitude M_R=-18.1 mag on JD 2457547. The brightness in the R band declined by 3.1 mag during170 days of observations. The rate of decline increased at thephase about 80 days past maximum. Comparison of the light and colorcurves of SN 2016ehw with those of well-studied type IIn SNeshows that this SN is quite typical for its classconsidering photometric evolution and maximum luminosity.
