Evolution of the spectrum FS Cma in 12 days with eshel spectrograph.
The spectrum of February 23th was made with a C14 (blue curve) compare with the 7th March spectrum taken with an RC 400mm Astrosib (red curve).
The spectrum of the lastnight is much more noisy because of the fog but also because the total exposure time is lower than for the first spectrum in february.
Somme change are visible in each curve (Halpha, Hbeta and HGamma)
