Dave Balam report/s a classification of object: SN 2016cct

Type: SN Ia
Redshift: 0.034

Remarks: A spectrum of ASASSN-16fa = 2016cct (ATEL #9045) was obtained using the 1.82-m Plaskett telescope (National Research Council of Canada) covering the range 375-710 nm (resolution 0.35 nm) on UT May 13.26 that reveals the object to be a type-Ia (normal) supernova near maximum light. Cross-correlation of the spectrum with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) has yielded a good fit to the type-Ia supernova 1996X at phase T = -1 day. The apparent host galaxy is UGC 6434 with a published (Huchra, J. P. et al., 2012, ApJ Supp. 199) redshift of z = 0.034. If we assume that the redshift is correct for the supernova then we measure an expansion velocity for the Si II (rest 635.5 nm) feature of 10,400 km/s.

The following Classification spectrum was provided:
