Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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
