Dr Skopal used V339 Del and Nova Cyg 2014 spectra of ARAS database in
order to dectect the Raman scattered OVI 1032 A.

A publication of a larger paper is ungoing.

If the analysis is confirmed, this should be the *first* detection of
the line 6825 A produced by this phenomenon in novae.
To date this line (and the fainter 7088) was detected only in symbiotic
stars and considered as defining feature of symbiotics.
See for explanations :

A great moment for amateur spectroscopy : a major discovery -if
confirmed- in the study of novae phenomenon, thanks to amateur
specytroscopy !

The co-authors are those whose spectra have been used by Dr Skopal.
Thanks to all observers and let's go on the observations of Nova Del
2013, Nova Cyg 2014 and Nova Cen 2013.

All the best,

François Teyssier

An important milestone for amateur astronomers, congratulation to all observers!

I just prepared an interpolated animation to show V339 Del Raman 6825 line evolution from 15 aug to 1 oct 2013 (Lhires III 600).

That's good Paolo, as usual
Ciao

I took my spectrum of nova V339 del trying to highlight the Raman emission line at 6825 A.

Here is what I get with animation of 36 spectra taken between August 14th and September 24th.

The emission line begin to appear on August 20th, then switched to a maximum 22 August and then decrease.


And the dynamic spectrum of the Raman emission line at 6825 A.


I will try to do the same with emission line at 7088 Å.
