77532020-10-21 16:48:00csogezaGeza CsornyeiadH0ccSN Ia-91T-like0.147adH0ccAn optical spectrum of SN 2020win, obtained on 2020 October 20 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V. The spectrum is similar to those of 91T-like peculiar Type Ia supernovae at, or a few days before, B-band maximum. GELATO finds good matches with SN 1995ac at a phase of 0 days, and with SN 1997br at a phase of -3.7 days at a redshift of 0.147. The redshift was determined through the fitting of the Ca H&K, the G-band, Mg I and Na D absorption lines of the host galaxy spectrum.2020TNSCR3201....1C
