Some unpublished ancient spectra of Nova Cyg 2014. Halpha at very high spectral resolution (R=47000 - Vhires),
but only 2 x 600 sec exposure (April 16):
and a medium resolution spectrum of red-yellow part (MEDRES spectrograph at R = 2000):

Excellent, Tim
It looks that the nova rebrightens.
Absorptions obvious, again
Very special behaviour
Waiting for for fit
I think the night will be clear here ...

MedRES version taken the May 15 (R = 2200 on C11, 9 x 600 sec exposure):
Note complex interstellar Na lines structure (two systems probable).

The last Nova Cyg spectrum

Rather surprised by the relative intensity of the Halpha line...
