Leighton Chajnantor Telescope

The Leighton Chajnantor Telescope (LCT) is a 10.4-meter submillimeter telescope in development for the Llano de Chajnantor Observatory in the Atacama Desert in Chile. The dish is to be that of the Caltech Submillimeter Observatory (CSO), now dismantled, which operated from 1985 to 2015 at Mauna Kea Observatories (MKO), Mauna Kea, Hawaii. As of April 2025, plans are first light in 2027. NEW-MUSIC is an instrument planned for it, undoubtedly a follow-on to an instrument on the CSO called MUSIC (for Multiwavelength Submillimeter Inductance Camera). LCT has also been considered as a future host for the Tomographic Ionized-carbon Mapping Experiment (TIME).
