Excellent reactivity! A rare event at this magnitude
(for me, permament bad weather on Toulouse
)

Fantastic, congratulations François!
Italy is under storms, weather forecasts say for another week...

Congratulations François!
I was able to get a spectrum through high altitude haze on June 16th (calibrated using HD208906 and the Miles spectrum).
Don't seem to be picking up the He II emission...

Thank you Paolo and Tim.
The changes in spectra of DN in outburst are very fast.
See for instance SS Cyg :

However I'll verify my images.
Could you send me your spectrum for the database, Tim?
All the best
François
