Sequence of optical spectra obtained of SN 2019wxt. The phase (in rest frame days relative to our adopted i-band maximum MJD 58835.1) is listed beside each spectrum. Telluric absorptions are indicated with a ⊕ symbol. In the case of the X-shooter, SPRAT and OSIRIS data, we plot a smoothed version of each spectrum, with the unsmoothed spectrum shown underneath in a lighter colour. Smoothed spectra have had a Savitzky-Golay filter applied, with window length of 50 Å for the X-Shooter data, and 100 Å for the SPRAT and OSIRIS spectra.
