Lemon (Lausanne) adH0cc SN II 0.026 1 adH0cc An optical spectrum of SN 2020upe, obtained on 2020 October 5 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V, shows a blue continuum with P-Cygni lines of hydrogen and helium superimposed. Based on the light curve, we estimate a phase of 9d after the explosion. The redshift has been measured from narrow host-galaxy H-alpha emission. 2020TNSCR3041....1T
