Blondin (CNRS, LAM) adH0cc SN II 0.04157 1 adH0cc The spectrum shows P-Cygni features of H and He, indicative of a young Type II supernova. Template matching with SNID yields a phase of about two weeks after the explosion. This is consistent with the flat Pan-STARRS light curve from 7 to 2 days before the classification. The flat continuum of the spectrum suggests significant interstellar extinction of around E(B-V) ~ 0.5 mag. We adopted the redshift of the host for the SN redshift. 2021TNSCR.880....1C
