Spectral observations of Seyfert galaxies at Fesenkov Astrophysical Institute (FAI), have been carried out for about 50 years, photometric observations in $BVR$ filters have been performed over the past 10 years. The telescope $AZT-8$ and two 1-meter reflectors located at the high-mountain Tyan-Shan Observatory (TShAO) are used for observations. In addition, archival spectral data obtained in 1970–1990 with an image tube and astronomical film, are used to reveal the long-term changes in selected Sys. Digitization of these archival materials is currently being carried out at FAI. In this paper, we present the results of the long-term observations of the Seyfert galaxy Mrk1095 (Ark120) and analysis of its photometric and spectral variability. According to the observations of 2007 - 2021, the variability of the continuum level and radiation fluxes in the emission lines in the spectrum of Mrk1095 was registered
