Blondin (CNRS, LAM) adH0cc SN II 0.03969 1 adH0cc The spectrum is characterized by a blue continuum with weak hydrogen and helium P-Cygni lines superimposed, indicating that this object is a young Type II supernova. We estimate the phase of the supernova to be 6-7 days, based on the ZTF non-detection 6 days prior to the observation. We adopted the redshift of the host for the supernova redshift. 2021TNSCR.445....1V
