TurattoPadova-AsiagoSN Ia-91T-like0.113Padova-AsiagoThe best match is with Type Ia-91T like SNe about one week before maximum light. The spectrum is very similar to SN 1998es spectra when a redshift of z~0.11 is assumed. From the very faint Si II 635.5 nm absorption an expansion velocity of about 11300 km/s is deduced.
