cds-question@unistra.frglobular-star-clustersinfrared-photometryvisible-astronomyWide-band photometryradial-velocitymetallicityWe present the first part of the first large and homogeneous CCD color-magnitude diagram (CMD) data base, comprising 52 nearby Galactic globular clusters (GGC) imaged in the V and I bands using only two telescopes (one for each hemisphere). The observed clusters represent 75% of the known Galactic globulars with (m-M)V<=16.15mag, cover most of the globular cluster metallicity range (-2.2<=[Fe/H]<=-0.4), and span Galactocentric distances from ~1.2 to ~18.5kpc. In this paper, the CMDs for the 39 GGCs observed in the southern hemisphere are presented. The remaining 13 northern hemisphere clusters of the catalog are presented in a companion paper. For four clusters (NGC 4833, NGC 5986, NGC 6543, and NGC 6638) we present for the first time a CMD from CCD data. The typical CMD span from the 22^nd^ V magnitude to the tip of the red giant branch. Based on a large number of standard stars, the absolute photometric calibration is reliable to the ~0.02mag level in both filters. This catalog, because of its homogeneity, is expected to represent a useful data base for the measurement of the main absolute and relative parameters characterizing the CMD of GGCs.2000A&AS..144....5Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/144/5CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/13 : Globular-Cluster Catalog (Arp 1965)VII/44 : Star Clusters Associations II.
