SOXS
The Son Of X-Shooter (SOXS) is a spectrograph instrument mounted on the ESO - New Technology Telescope (NTT) in La Silla.
SOXS has been built by a Consortium of institutes in Italy, Israel, UK, Chile Finland, and contribution from Denmark and Israel.

IMPORTANT
SOXS will have access to 180n/yr of GTO time. SOXS will be offered in P118 (ESO CfP link)
A policy document has been worked out together with the science cases (link)
Presentation of M. Schoeller at the SOXS day concerning the policies link (01/07/2025)
The protected SOXS GTO class of sources will be selected during P118. To have a non-exhaustive list of the class of sources and related observing times, you can have a look at the GTO proposals approved for P116.
Please have a look at these tables before submitting your proposals (link)
Please note that any questions concerning the ESO policies, target observability, GTO, etc. should be addressed to ESO.
