Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022). SN Ia subtype is currently unclear and redshift needs to be refined. ZTF lightcurve displays a brief (possibly cooling) early bump before its main rise to peak, somewhat similar to SN2019yvq/ZTF19adcecwu.2024TNSCR4040....1W
