RS Oph spectral journey

The deep sky guys have mentioned how red this recurrent nova was recently.
Well the spectrum tells the story.....
This is a compilation of RS Oph spectra taken over the past month.
It shows the dramatic increase of the H alpha line from x0.5 the continuum to x120 Almost a two hundred times increase
(This data was collected by my mate Jean-Bruno Desrosiers, in Quebec)
