The Southern Photometric Local Universe Survey

We describe the Southern Photometric Local Universe Survey (S-PLUS), a project that uses a dedicated robotic telescope, T80-South, to observe 9300 square degrees of the sky, from Cerro Tololo, with a unique set of twelve optical filters (5 SDSS-like and 7 narrow-band filters). The images in 12 bands, with a pixel size of 0.55 arcsec/pix and depths of 20.5 AB, are suitable for a number of studies that will be described in this talk. In particular, with S-PLUS one can identify large numbers of low-metallicity stars, identify quasars and estimate their redshifts and study groups and clusters, out to large radii, in the nearby universe, through precise galaxy photo-zs. The survey strategy includes: (1) the main survey covering the full area in all bands; (2) the ultra-short survey that allows studying bright stars; (3) the Galactic stripe survey, covering 1400 deg$^2$ in common with VVV and VPHAS+. The S-PLUS data are made publicly available to the international community through yearly data releases. The new S-PLUS results demonstrate the power of the 12-band system for Galactic and extragalactic studies.
