Blondin (CNRS, LAM) adH0cc SN II 0.0633 1 adH0cc The spectrum shows a blue continuum with P-Cygni features of H and He, indicative of a young Type II supernova. The ZTF and ATLAS light curves of the object suggest it to be about 6 to 10 days old, which is also supported by the convincing match with SN 1999gi and SN 1999em at 7 days found by GELATO (Harutyunyan et al. 2008, 2008A&A...488..383H). We have adopted the redshift of the host for the SN redshift. 2021TNSCR2990....1C
