21427 2025-06-28 16:17:13 Panos Charalampopoulos Panos Charalampopoulos (UTU) None SN Ia-91T-like 0.112 1 1 We report the classification of AT2025odm as a Ia supernova based on an optical spectrum obtained with the Nordic Optical Telescope on 2025-06-27 (i.e., MJD 60853.98). Comparison with a library of supernovae spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), suggests AT2025odm is an around peak SN Ia-91 T-like at a redshift of z~0.112 (Mg ~ -19.7). 2025TNSCR2458....1C
