Early −26 d spectrum of SN 2003G compared to LRN NGC 4490-2011OT1 close to the red maximum (Pastorello et al. 2019b), and to a F8 I type supergiant template (Pickles 1998). SN 2003G evolves spectroscopically into a SN 1994W-like event as shown by the comparison to SN 2009kn (Kankare et al. 2012). The early −26 d spectrum of SN 2003G also shows similarities to SN 2009kn close to the end of the plateau at +73 d. A line list used by Dessart et al. (2009) to model a synthetic late-plateau spectra of SN 1994W is shown as a reference for the early spectrum of SN 2003G, in addition to our identification of the plausible Ba Ii features.
