ESO, Garching, Germany, 6–8 May 2019
4MOST is a state-of-the-art, high-multiplex, optical spectroscopic survey facility currently under construction for ESO’s 4-metre VISTA telescope. During the first five years of operations 4MOST will be used to execute a comprehensive programme of both Galactic and extragalactic Public Surveys, and 30% of the observing time during this period will be available to the community. The process of selecting Community Public Surveys will be initiated by a Call for Letters of Intent for Public Spectroscopic Surveys, to be issued by ESO in mid-2019. In preparation of this Call, ESO and the 4MOST Consortium are jointly organising a workshop to prepare the ESO community for this exciting scientific opportunity, to assist potential PIs in successfully responding to the Call, and to foster scientific collaborations between the community and the 4MOST Consortium.
