Blondin (CNRS, LAM / ESO) adH0cc SN II 0.03426 1 1 adH0cc The SN shows broad P Cygni lines of H and He, indicating it is a Type II supernova. GELATO (Harutyunyan et al. 2008, 2008A&A...488..383H) found good matches with canonical SN II spectra two weeks after explosion. We adopted the redshift of the host for the supernova. 2025TNSCR1136....1C
