Caption: Figure 7.

Continuum-normalized moderate-resolution SOAR/Goodman spectrum taken on 2017-11-15. Double-peaked emission lines of He I at 5875 and 6678 Å and H I at 6563 Å from the accretion disk are evident, as are the numerous narrow metal absorption lines from the secondary. The resonance Na I line is a blend of absorption from the secondary and the interstellar medium.
