One spectrum a day should be perfect

[OI} very intense. Low density and low excitation.
Very peculiar behaviour for a nova.

That's great Paolo,
The two absorptions in the blue edge of H alpha line are clearly seen ; the complex structure of the flat top of [OI] also
See you soon

June 23rd spectrum.
Seeing was very good and slit efficiency was relatively constant so I decided to calibrate to flux.
I am using HD190603 and its Miles spectrum M(V) 5.66 for the calibration.

Nova Cyg is brightening again.
Here is my June 27 spectrum compared to my last June 23 result. Both in absolute flux.
