Abstract

Here are the results of the observations of the nuclei of the Seyfert galaxy of the first type NGC 7469 carried out in the period 2016-2019 BVRI. Observations were carried out on the telescope "SEİSS 600" of the Shamakhy Astrophysical Observatory named after N.Tusi. It is reported that discovered from observations of 2016-2019 in the core of the active galaxy NGC 7469 there were 3 flares. The first flare was the most powerful, and the amplitudes of change in brightness was in the BVRcIc filters approximately:ΔB = 0.272; ΔV = 0.181; ΔRc = 0.173; ΔIc = 0.125 magnitudes. The second flare of average power and brightness changes was in the BVRcIc filters respectively: ΔB = 0.098; ΔV = 0.047; ΔRc = 0.093; ΔIc = 0.036 magnitudes. And the third flash is comparable to the first flash and the change in brightness was in the BVRcIc filters, respectively: ΔB = 0.207; ΔV = 0.168; ΔRc = 0.119 ;ΔIc = 0.065 magnitudes.
We believe that this may be the result of active star formation in the Seyfert galaxy of the first type NGC 7469, as well as the reason for this may be the interaction with the IC 5283 galaxy. The amount of free gas in this galaxy should be greater for this reason. As a result, this leads to a change in the rate of accretions to the core of the galaxy.
