ZTF

Spectrum is well-fit to template spectra from various SN Ia subtypes from previously classified events. Broad wings can also be seen by eye for the H-alpha profile. This, combined with the event's slowly evolving lightcurve peaking at M_r ~ -20.8, motivates us to classify this event as a SN Ia-CSM. Redshift of z = 0.154 found using H-alpha emission in spectrum. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022).
