  SOXS (Son Of X-Shooter) is a single object spectrograph offering a
simultaneous spectral coverage from U- to H-band, built by an international
consortium for the 3.58-m ESO New Technology Telescope at the La Silla
Observatory. It is designed to observe all kind of transients and variable
sources discovered by different surveys with a highly flexible schedule
maintained by the consortium, based on the Target of Opportunity concept. SOXS
is going to be a fundamental spectroscopic partner for any kind of imaging
survey, becoming one of the premier transient follow-up instruments in the
Southern hemisphere. This paper gives an updated status of the project, when
the instrument is in the advanced phase of integration and testing in Europe,
prior to the activities in Chile.
