Evolution of the Bowen+Hβ (top) and Hα (bottom) Balmer emission lines observed through the five epochs of FLOYDS spectroscopy. Grey dashed lines match those in Fig. 8. Epochs 2020-05-31 and 2020-06-06 were of low S/N in the blue wavelength range, and thus are omitted from the plot here. The minor evolution of the Hα peak position over the FLOYDS spectra was deemed to be most likely due to aperture-related effects during observations.
