Our moderate-resolution spectra of SN 2023gpw. Savitzky-Golay smoothing has been applied, and the +12-d spectrum has been binned by a factor of five. The original spectra are plotted in gray. The zero epoch corresponds to the g-band peak on MJD = 60085.0. Telluric absorption is marked with the ⨁ symbol and vertical dotted lines. The +278-day spectrum has no clear SN lines; only narrow emission lines from the host galaxy can be seen. Extinction correction has not been applied. The public PESSTO spectrum at +15 d does not include telluric-line correction.
