PNV J17261813-3809354
From the discovery by Andrew Pearce that was the subject of this CBAT: http://www.cbat.eps.harvard.edu/unconf/followups/J17261813-3809354.html We made its spectrum last night with our eshel setup (R=11000). Just 3 exposures of 1200s before sunrise. The target was at magnItude 6.4 at the time of the ...

Our dual spectro setup (low and medium resolution) works perfectly. https://i.postimg.cc/Ls5MMvxM/SETUP.jpg - 1 year remote in Chile for eShel (R=11000) https://i.postimg.cc/jqFc8c77/LESIA.jpg - almost 3 years for the Alpy 600 (R=570) At present, we produce spectra automatically every night (acquisi...

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. https://i.postimg.cc/jdjFB55C/Nova-Sco-time-serie-Web.png And some animations on the lines: H alpha https://i.postimg.cc/fW8H7NKs/Nova-S...

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: R Aqr Eclipse - Monitoring requested
R Aqr taken this morning from Chile with a window of only 2 hours before dawn. the full spectrum with an eShel (R=11000), the target is about mag. V=11,5 https://i.postimg.cc/sgZXK5KD/R-Aqr-full-Web.png and some evolution from our last spectrum taken in november 2022 with a whoppshel (R=30000) https...

Re: PNV J17224490-4137160
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 allowe...

Re: PNV J17224490-4137160
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. https://i.postimg.cc/SQPsfHQb/Nova-evolution-full-1-2-mai-2023-Web.png https://i.post...

Re: PNV J17224490-4137160
No spectrum today because of bad weather in Chile.
