The spectrum is quite flat, as of last night at least, but as the nova starts to fade the emissions should show through again, with the H-alpha emission dominating. I've attached my low-res spectrum from 19 June showing the flat spectrum, with a narrow absorption at H-beta and possibly absorption & very small emission at H-alpha (p-Cygni profile). Hi-res spectra at the ARAS group confirm this. Will be interesting to see if the emissions show tonight!
