The LSST will be built on Cerro Pachón, a mountain located on property owned by the Association of Universities for Research in Astronomy, Inc. (AURA). AURA is permitted to operate telescopes in Chile because of an agreement reached with the Universidad de Chile (UCH) at the time Cerro Tololo Inter-American Observatory was established. AURA and UCH, in close consultation with LSST Corp. (LSSTC), have now extended that agreement to cover operations of the LSST. “The goal of all the parties engaged in the negotiation was to ensure that the principles for operation of the LSST would enable full participation of Chilean astronomers in all aspects of the LSST project from planning to analysis of the data,” says Sidney Wolff, LSSTC President.
