Optical spectra of J0408−38 taken with VLT, SAAO 1.8m, and SALT. The flux has been re-scaled for all the spectra using the [O III] λ5007 emission line. Prominent emission lines are marked. In the inset figure, we show the window range of 4550–4800 Å; spectra are scaled to have matching continuum levels. The He IIλ4686 emission line fades dramatically over the course of the observations.
