We observed the cluster of galaxies A3556 (< v > = 14300 km/sec), belonging to the supercluster of galaxies known as the Shapley Concentration (Bardelli et al., 1994, MNRAS 267, 255, and references therein), with the Australia Telescope Compact Array. Our observations took place in the continuum band at 20 cm with the configurations 1.5D and 6C, and at 20 cm and 13 cm in the configuration 6A, for a total of 12×3 hours, with a resolution ranging from ≃ 6″ to ≃ 40″. We observed a sky region of ≃ 2° × 1° around the cluster center taking advance of the mosaicing technique developed ATNF.
