2SPOT est une association loi 1901 reconnue d'intérêt général créée en 2019 par 5 astronomes amateurs afin d'installer un observatoire pilotable à distance au Chili.
Essentiellement dédié à la spectroscopie, 2SPOT a pour but de contribuer à divers programmes de collaboration pro/am. Le matériel a été installé au Chili courant Mai 2021.

!!! ALERT NOVA !!!
Monitoring of the new discovered Nova Sco 2023 (PNV J17224490-4137160) | | 24 Avril 2023 - Thomas Petit | | According to an alert emited a few days ago, we decided to make some spectra of this new discovered nova as soon as possible. We were able to provide optical spectrum of nova Sco 2023 after the alert. The spectrum was taken on Saturday 22nd of April with our medium resolution eShel spectrograph (R=11000). We plan to follow up the target in the next few days and weeks at medium resolution and then at low resolution with our Alpy spectrograph (R=600) as the luminosity of the nova decreases.
Here are the results we obtained and some more useful information...

Fig 1: The figures show animations of the temporal evolution of the spectrum. The data is interpolated between our daily acquisitions. There is no real scientific value in these animations except that small variations in the spectrum become more obvious. (left is full spectrum and right is Ha line) |
