Here are some more LhiresIII spectra of V0694 Mon done before inclement weather set in (used HD071155 at instrument calibration reference star):
Ha region:

Hb region:

There were quiet a few emission line around the emission spike of the H-Beta line; I could only identify the FeII line around 4923.92A.
Just a few more weeks before this goes too far west and too low for high quality spectrum.

Another spectra between Southern California rain storms....V0694 Mon around CaK:

There has been a decrease in the H-zeta & CaK line activity as compared with the 08Feb18 spectra. Of course, since this band
is susceptible to poor atmospherics, it might be that these lines suffered from UV absorbing aerosols and/or low altitude observation.
