(a) Hα profile from our sequence of low-resolution spectra plus the initial +25-day spectrum obtained by Terreran et al. (2016). The profile is asymmetric with a redshifted broad base, a strong intermediate-width component, and a narrow peak. (b) Zoom-in on the region surrounding Hβ where the most prominent Fe II lines are located that form broad features with superimposed narrow peaks.
