PESSTO (for Public ESO Spectroscopic Survey of Transient Objects) is a survey of transients being carried out on the New Technology Telescope (NTT) using instruments EFOSC2 (optical) and SOFI (near infrared), including some low-resolution spectrography. It classified reported transients into supernova types, or AGN activity, variable stars, tidal disruption events, supernova impostors, or other optical transients (or solar system objects). Thousands of transients have been classified. The original PESSTO ran from 2012-2017 followed by an extension (ePESSTO) running into 2019, their SSDR 4 (spectroscopic survey data release 4) with 7 years' data was published in 2021. Following was ePESSTO+, an additional extension to continue the program. This will operate until the commissioning of a future NTT instrument that is in development: SoXS (Son of X-shooter), which I presume to be modeled on European Southern Observatory Very Large Telescope's X-shooter wide-band spectrograph.
