Pastorello (INAF Padova)Padova-AsiagoSN Ia-91T-like0.067Padova-AsiagoThe spectrum is consistent with those of SNe Ia-91T-like few days before maximum. The expansion velocity deduced from the Si II 635.5 nm absorption is about 10000 km/s. The redshift is from narrow lines of the host galaxy, which is different from the photometric redshift (0.051) reported by SDSS. 2020TNSCR3399....1T
