Hi all, thanks to some observations made from 23 Nov 2016 to 25 Jan 2017 I create an animation showing the CIII 5696 line evolution. I used ISIS animation tool, adding a bar indicating when the profile is not real but interpolated.
As we have seen for other animations and profile comparisons in this thread, the excess emission move from the blue side toward the red side of the flat top CIII 5696 line during the periastron passage, reflecting the shock cone radial velocity development:

(dash-dotted straight line is the our line of sight)
Radial velocity extent is very large, perhaps I should have used RVs instead of Angstroms for the abscissa graph.

Hi Paolo,
Great animation !!!
have you send your data to Noel Richardson ?

Re: WR140 aproaching periastron
Dear friends, thank you for your comment!
Olivier, I sent them the animation (in addition to the spectra) and prof Moffat posted it on WR 140 Wiki main page (I'm glad they also appreciated). I'd have liked to take more spectra to better interpolate but, let'say, some natural events in the centre of Italy prevented me doing so.
Clear sky!
