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.

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



And the H alpha velocity progression in 2 days

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)

[2SPOT]

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

[2SPOT]

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

Here is the evolution over 5 days



H alpha evolution since 5 days

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

No spectrum today because of bad weather in Chile.
