A better spectrum from france but large absorption (it is spring here) + urban pollution + windy conditions...
):
Below, addition of (not ideal) three nights observations result (cumulative exposure
of 4h20m ! 24 + 25 + 27 /07):
The 5015 A line is probbaly detected, but 5875 A features is not clearly visible at this
SNR for the moment.

Toujours avec un T200 mm et un Alpy600, mais en direct de l'Observatoire de Haute Provence (OHP)
où le ciel est tout de même plus transparent qu'aà Toulouse (7x600 s avec du vent au début) :
Evolution il semble depuis les derniers spectres de Terry (25/07).

My lastest from Observatoire de Haute Provence. Better...
Trace of P-Cygnii profile is now visible.
A 2D image taken this night (Alpy 600 + 200 mm):

The August 1, 2013 spectrum from OHP2013:
A very excellent night (seeing, transparency, no wind). I have also adopted
a standard 23 microns slit for the Alpy600, for a resolution spectral power of R = 590 in the red (18 microns last
nights, for a R = 650).
The SNR increase (note clear detection of Balmer lines 4340, 4101 and 3970 A).

The nova at the same place of Christian, at the same date and time with a LISA and C14 at f/d7
13 exposures of 600 secondes with ATIK 460EX in binning 2x2

Spectra from 9/8/13
3 x 600sec at an airmass of 1.01. Nice to have a target essentially straight up.
It is getting brighter and now has a mag of V = 12.66
The spectra demonstrated a reduction in the strength of the Ha line and increasing P cygni effect.
