Lemon (Lausanne)adH0ccSN Ia0.07adH0ccAn optical spectrum of SN 2021abi, obtained on 2021 January 15 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V, is similar to those of several normal Type Ia supernovae a few days before B-band maximum. SNID identifies SN 2003du around day -5 as the best match. A redshift z~0.07 is estimated from the SNID crossmatches.2021TNSCR.171....1L
