Hello all,
Yes Olivier, such animations are indeed very valuable to understand a little better the dynamics of the phenomenon !
Thank you François for this information, it's always very interesting to see that the spectra of the ARAS database are appreciated and can be useful in such studies !
To complete the discussion on RS Oph, here is a paper published in MNRAS which refers to the 2006 outburst and presents the evolution of its spectrum over about 250 days :
"Optical spectroscopy of the recurrent nova RS Ophiuchi – from the outburst of 2006 to quiescence" (Mondal 2018)

In particular, the evolution of the Fe lines at 5303 A [Fe XIV] (figure 15) and 6374 A [Fe X] (figure 16) are mentioned in this paper.
