My last observation, 12.9 aug 2014. Two Miles reference stars for flux calibration, HD 176301 and HD 196544.
4.9 and 12.8 august comparison of the same spectral range.
During large slit operations (long exposure guide camera frame). Target is slightly slit off-axis to avoid contamination by a field star.

Nova Cyg for Sept 17 calibrated for flux.
Multiplying by the V Bessel function gives a V magnitude of 12.65, in very good agreement with AAVSO data.

Very fast evolution,
noticelly [OIII] lines
A daily coverage should be usefull for a few days

Thanks to Joan and Antonio 's spectrum, we can establish that the "[OIII] flash" occured precisely between 20.9 and 21.8 of september

A spectrum taken the 19.9 / 09 / 2014, not perfect but can help for follow fast evolution.
Peculiar spectrum because it is one of the first light of setup presented here
