Blondin (CNRS, LAM)adH0ccSN II0.03969adH0ccThe 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
