Luckily I was out last night (7th) taking another spectrum of the nova but with slightly better resolution.  As soon as I found the field in the finderscope it was obvious the nova had brightened significantly. The spectrum now shows very well defined P-Cygni features on most of the emission lines.

Astronomer’s telegram ATel14614 gives a nice update on the nova’s evolution.
