For the name of this target can we call it : Nova Sco 2023 or PNV J17224490-4137160 ?

Congratulations to 2SPOT for a job well done, from another southern hemisphere (Australia) eShel observatory.
Unfortunately this nova is not visible to me until very late at night.

Unfortunately, my weather is all cloud, or rain, these days so It is a case of 'If I could, I would, but I can't'.

Nova Sco 2023 sera parfait.

Je rajouterai PNV J17224490-4137160 dans le header.

Hello Hamish,

The H Alpha order is the bright and broad line at the bottom of the spectrum.
Soon the first graphes with a partial set of data.

Here are some provisional graphs that cover the first 2,5 hours of total exposures. We are waiting for the end of the current observations to process everything (dawn starts in 2 hours in Chile)

Le full spectrum with 8 exposures of 1200s each.

We process all our data (16 spectra of 1200s each) and separated in 2 groups of 8 spectra.

Here's the evolution in 3 hours

Excellent

The page in the database:
https://aras-database.github.io/databas ... o2023.html

with the spectra secured by 2SPOT and Sean Curry.

Monitoring as far as possible is encouraged
