LiONS

The spectrum obtained through 2.4m LJT matches a 91T-like SN Ia at a few days before peak (e.g., SN 2001eh at t = -5 d via SNID), which conforms the previous Type Ia-91T-like SN classification by Claudio Balcon.

SN Ia-91T-like

0.02

GELATO (Harutyunyan et al., 2008, A&A, 488, 383) and DASH (Muthukrishna et al., 2019, ApJ, 885, 85) suggest that this low S/N spectrum resembles that of type Ia-91T-like supernova about one week before Bmax at a redshift 0.02. GELATO suggests also a possible matching with a type Ic-BL supernova.
