18482 2024-10-31 09:47:42 Panos Charalampopoulos Panos Charalampopoulos None SN Ia 0.097 1 We report the classification of AT2024led as a Ia supernova based on an optical spectrum obtained with the Nordic Optical Telescope on 2024-10-31 (i.e., MJD 60613.85). The transient is coincident with the nucleus of the host galaxy (SDSS spectroscopic redshift of 0.097). Comparison with a library of supernovae spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), suggests AT2024led is a pre-peak SN Ia (and potentially a SN Ia-91T-like). 2024TNSCR4247....1C
