  Context. The populations of small bodies of the Solar System (asteroids,
comets, Kuiper-Belt objects) are used to constrain the origin and evolution of
the Solar System. Both their orbital distribution and composition distribution
are required to track the dynamical pathway from their regions of formation to
their current locations.
  Aims. We aim at increasing the sample of Solar System objects that have
multi-filter photometry and compositional taxonomy.
  Methods. We search for moving objects in the archive of the Sloan Digital Sky
Survey. We attempt at maximizing the number of detections by using loose
constraints on the extraction. We then apply a suite of filters to remove
false-positive detections (stars or galaxies) and mark out spurious photometry
and astrometry.
  Results. We release a catalog of 1 542 522 entries, consisting of 1 036 322
observations of 379 714 known and unique SSOs together with 506 200
observations of moving sources not linked with any known SSOs. The catalog
completeness is estimated to be about 95% and the purity to be above 95% for
known SSOs.
