Description
I present ultraviolet, X-ray, and gamma-ray analyses of Swift and Fermi-LAT observations of the narrow-line Seyfert 1 galaxy 1H~0323+342, obtained between late September and mid-October 2025 (MJDs 60939.977–60961.620). The source underwent a recent outburst (ATel 17411), which prompted a multiwavelength investigation. The main goal of this work is to study its X-ray spectral evolution in connection with ultraviolet magnitudes and flux densities, gamma-ray emission, and variability amplitude, in order to explore the interplay between the accretion disk, corona, and relativistic jet. Furthermore, through ultraviolet extrapolation, I assess its suitability as a target for upcoming UV space missions, with particular emphasis on the Czech UV mission QUVIK.
