		| Abstract: | 
		I present results of my observations of Seyfert galaxy during 1986-2001 carried out with UBV photometer at 0.6-m telescope of Crimean Laboratory of Sternberg Astronomical Institute. UBV magnitudes show the strong changes during this period. I have analysed the lightcurves by computing the normalised power density spectrum and structure function. |
