21299 2025-06-14 00:10:26 Claudio Balcon Claudio Balcon (Belluno A.O. ISSP) None SN Ia 0.036713 1 Using GELATO (Harutyunyan et al., 2008, A&A, 488, 383; (gelato@tng.iac.es)), we find that the spectrum resembles that of a Type Ia supernova at the redshift of the host galaxy. However, the original spectrum is contaminated by the nucleus of the host galaxy. To obtain the spectrum of the transient, we subtracted the spectrum of the nucleus (SDSS ID 682361628800346112) from the original one. 2025TNSCR2220....1B
