2SPOT is a non-profit organization created in 2019 by 5 amateur astronomers in order to install a remote observatory in Chile.
    Mainly dedicated to spectroscopy, 2SPOT aims to contribute to various pro/am collaboration programs. The equipment has been installed in Chile during May 2021.


    AGENDA:

 July 2023 Spectro Party at OHP
 November 2023 Mission to Calern

Nova Sco 2023
Monitoring of the new discovered Nova Sco 2023 (PNV J17224490-4137160)
    24 April 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...

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)
