SLSN-I

0.039

ZTF

Spectrum is well-fit by SLSN-I templates from previously classified events. A redshift of z = 0.0390 ± 0.0002 was found using host emission lines. Lightcurve has been rising for ~48 days so far and the transient now has a magnitude of M_r ~ -19.2. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022).
