Spectral evolution of SN 2020faa. Labels indicate the days after the explosion. Spectra in gray are from Y21, while the spectra in black were reduced by us. All spectra are reddening- and redshift-corrected and matched in intensity with respect to the Hα emission and arbitrarily shifted for better visualisation. All spectra are galaxy template-subtracted (see Fig. 6 and text).
