(Top): Asiago/Echelle spectrum (−8 d, blue curve) and Lick/APF spectra of SN 2020ue. (Bottom): Lick/APF spectra of SN 2020nlb. The spectra were obtained around the peak brightness of both supernovae. The grey regions mark the positions of the expected Na ID lines at the redshift of each supernova, accounting for a shift of ±100 km/s due to possible rotation velocity at each supernova position.
