Smartt, M. Dobson (QUB), R. Kotak (Turku), R. Bruch, A. Gal-Yam (Weizmann), C. Lemon (Lausanne) adH0cc SN Ia 0.0906 1 adH0cc An optical spectrum of SN 2020ver, obtained on 2020 October 13 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V, shows it to be a Type Ia supernova. The spectrum is similar to those of normal Type Ia supernovae about a week before B-band maximum. GELATO found good matches with spectra of SN 2003kf at the epochs of -6 and -7 days. The redshift was determined based on the wavelengths of narrow emission lines of the host galaxy. 2020TNSCR3119....1C
