The spectra also reveal relatively narrow width absorption features of Fe II, Si II, and Ca II in the photospheric phase with a blueshift of around 13,000 km/s. The spectra best match Type Ic SN 1994I, and the Type Ia-pec SN 2005hk using SNID (Blondin & Tonry 2008) and NGSF (Howell et al. 2005). The source is clearly a SN I, but at present, we can not unambiguously distinguish between a stripped-envelope Type Ic and a bright thermonuclear SN Iax. 2024TNSCR3894....1S
