TNS Classification Report No. 7945 [ 2020TNSCR3399....1T ]
Date Received (UTC): 2020-11-09 11:08:01 Sender: Lina Tomasella
Group: Padova-Asiago
L. Tomasella, S. Benetti, E. Cappellaro, N. Elias-Rosa, A. Pastorello (INAF Padova) report/s a classification of object: SN 2020yyg
Type: SN Ia-91T-likeRedshift: 0.067
Remarks: The 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.
