Hi Nigella,
Looks good to me, you’ve got the strong H alpha emission along with H beta and some iron lines (I think). Also the atmospheric absorption bands in the red/IR. If you are new to spectroscopy that’s a great start!
The latest Astronomer’s Telegram, ATel#18021 reports the rapid evolution of the spectrum over just a few days and the fact that this is a “Fast” nova. So take a look at every opportunity before it gets too faint.
Mike.
