Evolution of the Hα (black) and He IIλ4686 (red) line profiles in SN 2023gpw with the continuum subtracted on both sides. Telluric lines around Hα (⨁) are marked with dotted lines and the zero velocity with a dashed line. A weakening narrow component can be seen in the profile, while the wings of the broad component are disturbed by the telluric lines, but extend to several thousand km s⁻¹ on both sides.
