20565 2025-03-13 08:29:39 Panos Charalampopoulos Panos Charalampopoulos None SN Ia 0.079 1 We report the classification of AT2025dbn as a Ia supernova based on an optical spectrum obtained with the Nordic Optical Telescope on 2025-03-12 (i.e., MJD 60747.24). The transient is coincident with the nucleus of the host galaxy. Comparison with a library of supernovae spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), suggests AT2025dbn is an around peak SN Ia at a redshift of z~0.079. 2025TNSCR.978....1C
