U Sco is signaled in nova eruption
The novae events of U Sco are very fast.
Thus monitoring on several hours during the night will be very usefull,
to be followed bu our colleagues in America and Australia.
Spectra of the event welcome on the database !

raining here in south island of new zealand, but if it clears tonight (it's 2pm local time now) I will try.

Here is a first view of the spectrum of the recurrent nova U Sco.

Salut à tous, je poste mon profil de la nova avec le réticule 2400/mm centré sur le H-alpha

And a spectrum taken from Chile this morning with a Prism scrip (automatically made by Prism Software with no human intervention)



We will try it from France with eShel spectrograph, but the target is very low in altitude.....

j'ai essayé d'envoyer notre spectre à la base ARAS sans succès, à chaque fois on a un message d'erreur de gmail disant que notre message n'as pu être délivré.

Great early spectra ! The evolution is very fast in just a few hours compared with the description of the spectrum in ATel 15420 taken 2022-06-7.48

It might be too low for me but I will try if the clouds clear

Very fast evolution of U Sco (and a very special spectrum), from Antibes (France), Star'Ex spectrograph on a Celestron 9.25 telescope, the 7.880-06-2022:

Voici le profil du 07/06/2022 même configuration meilleure transparence du ciel.

Nice work everyone!

Changes are occurring rapidly!

Here is a comparison of flux calibrated spectra over two nights as the V magnitude dropped from 7.957 +/- 0.072 to 9.484 +/- 0.024 taken with a LISA and processed using ISIS.
