We note however there is significant contamination from the underlying host galaxy in the spectrum. We determine a redshift of z = 0.143 from narrow host emission lines. At this redshift the peak absolute magnitude of the SN is significantly brighter than normal SNe IIP at M_r ~ -20.6. 2023TNSCR.207....1G
