Bonsoir François, sur la nouvelle j'ai atteint R = 8200, mais je préconise d'améliorer la technique d'acquisition.Bientôt, je vous enverrai le spectre
Cordialement.

Bonjous à tous,

... et mes felicitations à tout le monde pour tous ces magnifiques spectres et le travail publié au CBAT. Cette nova est très très intéressant et la seule chose que j'ai à regretter est qu'elle sera de plus en plus difficile d'observer pour la proximité au soleil...

J'ajoûte le dernier spectre (résolution mediocre, désolé) et un stack avec tous mes spectres pour comparer l'évolution de la nova.

Here is my result for 2017-09-20 at R = 13000. Vmag starting to declining again.

My results for the evolution of H alpha and H beta since 2017-09-10, just before the latest maximum.

Hi,
In these graphs, it is seen, the evolution of Halpha of NOVASCT2017 in the last 5 days.
The Halpha, again, shows a strong upward trend, Until when?

Hello,

This is an example of the evolution of the Halpha of Nova Sct 2017, from 20170726 to 20170923.

For the GIF, used 35 observations were collected with Mussol and Linx.

Friendly, Joan.

Grazie Umberto,
It seems the NovaSct2017, is preparing another outbrust.
Un abbraccio, Joan.
