20913 2025-04-28 11:21:31 Panos Charalampopoulos Panos Charalampopoulos None SN Ia 0.085 1 1 We report the classification of AT2025htf as a Ia supernova based on an optical spectrum obtained with the Nordic Optical Telescope on 2025-04-27 (i.e., MJD 60793.01). 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 AT2025htf is an around peak SN Ia at a redshift of z~0.085. 2025TNSCR1571....1C
