Another spectrum taken this morning.
The evolution of the nova day after day, is smaller and the magnitude continues to decrease to mag. V=9,75, but we still manage to make its spectrum with the eShel spectrograph.

We continue to produce one spectrum per day (or rather every night) since April 22.
on our side with the eShel spectrograph and also thanks to Sean Curry who remotely controls a UVEX setup located in Australia (the one of Peter Velez)
This daily production of spectra from the south hemisphere allowed us to have this ATel :

And all spectra are in the ARAS database here :

the novae decreases little by little and is currently at magnitude V=10,8 according to the AAVSO measurements.

Re: PNV J17224490-4137160
Our last spectrum from this morning taken in bad conditions (some clouds during observations).
The novae is at mag. V=11 but we could take a spectrum with the eShel.

Re: PNV J17224490-4137160
we have been following this nova day after day for 2 months now.
Here is a graph showing the global evolution of the spectrum with all our spectra acquired so far.
And some animations on the lines:
H alpha
H Beta
HeI 5876
