Andrew Howell, Stefano ValentiLCOGT SN-KPSN Ia0.02LCOGT SN-KPUsing SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several normal and 91T-like Type Ia supernovae 2-3 weeks after maximum light at redshifts around z=0.02. This confirms the classification and redshift of Falco et al. (2016, <a href="http://www.astronomerstelegram.org/?read=9118">ATel #9118</a>).
