This dataset contains the visible spectra of 820 asteroids obtained between November 1996 and May 2001 at the 1.52m telescope at ESO (La Silla). The useful spectral range is between about 4900 and 9200 Angstroms. The global spatial distribution of the objects covers the region between 2.2 and 3.3 AU. Some concentrations are apparent, since part of the survey was focused on particuarly interesting groups or families of asteroids. The observed asteroids have been classified according to the Tholen and the Bus taxonomies, with a good agreement between both in most of the cases. These data are presented and discussed in Lazarro et al. (2004).
