20194 2025-01-17 19:36:40 Claudio Balcon Claudio Balcon (Belluno A.O. ISSP) None SN Ia 0.03 1 GELATO (Harutyunyan et al., 2008, A&A, 488, 383) suggests that this low S/N spectrum resembles that of a type Ia supernova. The redshift has been deduced from the SN spectral fitting. The spectrum is reddened and polluted by the host. 2025TNSCR.229....1B
