Spectrum is well fit to SN Ic and SN Ia templates using Next Generation Superfit (NGSF, Goldwasser et al. 2022). However, lack of prominent Si II absorption and a peak absolute magnitude of g ~ r ~ -18 suggests SN Ic. Redshift obtained from host galaxy emission lines. It should be noted that this event is coincident with the position of the event 2002kj.
