Scientific paper

Based on the international AGN watch of NGC 4151 groundbased optical observational data, some significant periods of NGC 4151 light variation are obtained by means of the periodogram analysis and stepwise regression analysis. There exist two major periods. One is about 14 d for all bands. Another is about 30 d for all continuum bands, but 24 and 38 d for Hα and Hβ, respectively.
