We present results of multicolor UBVRI observations of the type 1 Seyfertgalaxy (SyG 1) NGC 7469 carried out at the 1.5-meter telescope of the MaidanakObservatory (Uzbekistan) in 2008-2014. Analysis of the light curves indicatesthe presence of another slow flare of a long-term variability in 2009-2014 witha maximum in 2011-2012. We investigate properties of the long-term variabilityin 2009-2014, present (U-B)-(B-V) color diagrams for maxima and minima of NGC7469 nuclear variability using various apertures and compare them with theblack-body gas radiation which models the accretion disk radiation. Color-indexmeasurements shows that the color becomes bluer at maximum brightness,indicating a higher temperature of the accretion disk. We have analysed therelation of X-ray and optical variability of NGC 7469 in 2008 and 2009 incomparison with the activity minimum in 2003. In 2008 the correlationcoefficient between the X-ray and optical radiation is close to 0.5. Such poorcorrelation can be explained by the influence of an SN 1a explosion in closeproximity to the nucleus of NGC 7469. The SN manifests itself in the opticalband but does not affect the X-ray variability pattern. Comparison of thevariability data in 2009 reveals a good correlation between the optical (Uband) and the X-ray (7-10 keV) variability with the correlation coefficient ofabout 0.93. The correlation coefficient and the lag depend on the wavelength inthe optical and X-ray bands. The lag between the X-ray and optical fluxes in2009 is 2-4 days. In 2003 the lag is almost zero.
