ATel for the first spectrum :

This morning there was quite a lot of cloudy passages in Chile but we could make a spectrum of the Nova and which rises in 24H of big evolutions.



Here is the comparison of 2 spectra at 24 hours interval. The blue part/Near UV of the last spectrum is very noisy because of the clouds.




And the H Alpha velocity graph show the evolution in only one day.



Tomorrow a new spectrum if the weather in Chile allows it.

A second ATel for this Nova :

Our daily spectrum taken this morning and comparison with the 2 previous days.



And the H alpha velocity progression in 2 days

and a confirmation from IAU about our first spectrum :

Now this Novae Sco 2023 have a name = V1716 Sco

We can take one spectrum per day at this moment with a eShel spectrograph for the moment with the eshel spectrograph as long as the magnitude of the nova allows it (and the weather too)

For the moment we can follow the nova every day with a new spectrum. The goal is to cover a maximum of days with the eshel spectro as long as the nova's magnitude allows it.

Here is an animation made with all our spectra made so far.



And on H alpha line animation

We continue to follow the nova with one spectrum per day.

Here is the evolution over 5 days



H alpha evolution since 5 days



Animation on H alpha line



and a 2D dynamique représentation on H Alpha

Our daily spectrum of this morning (with some clouds during observations)

No spectrum today because of bad weather in Chile.
