From the discovery by Andrew Pearce that was the subject of this CBAT:
http://www.cbat.eps.harvard.edu/unconf/ ... 09354.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 exposures.

The spectrum was produced automatically this morning

Here's the automatic pointing of the target on the spectrograph fiber


and the full graph automatically processed


as well as the graph of Balmers lines up to H gamma (H Delta being very weak)

An interesting very red spectrum. Total galactic IS extinction is 7.8 in V in that direction so probably very reddened. Image how bright it might have been without extinction !

A second spectrum taken this morning and the evolution in one day.

Official name is now V1323 Sco

Excellent!

Bonne continuation!

Another spectrum taken this morning and the evolution since 2 days

ATel for this novae with our 3 spectra :

Our observations continue at the rate of one spectrum per day.

Here is the evolution over the first 5 days of this novae
Evolution of the whole spectrum



And the H alpha évolution

Our 9th spectrum of this nova, i.e. one spectrum per night without interruption

Observations of this nova continue from Chile, with 1 spectrum per day for the last 12 days, always in automatic observation and including the spectra process, so we don't have to do anything manually.

Here are our 12 spectra and their evolutions



and H alpha line evolution
