Lemon (Lausanne) adH0cc SN II 0.04185 1 adH0cc An optical spectrum of SN 2020abty, obtained on the night of 2020 December 10 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V, shows it to be a Type II supernova. The spectrum shows a blue continuum with weak H features. The spectrum along with the photometric measurements from ATLAS indicate that this is a young supernova, with a phase of 7-8 days. The host redshift is known from SDSS observations. 2020TNSCR3754....1C
