Patra (UCSC) UCSC SN Ib 0.02 1 UCSC The best SNID-SAGE matches are to SN Ia and Ib templates near peak brightness at z ~ 0.02. Assuming that redshift and no host-galaxy extinction, the current absolute magnitude (M_clear = -16.3 mag and not rising quickly; Kono et al. 2026, TNS AT Report 320187) is more consistent with that of a SN Ib than a SN Ia. 2026TNSCR3402....1K
