The observations were conducted with the InfraRed Survey Facility (IRSF), a 1.4-m telescope situated at the South African Astronomical Observatory (SAAO) in Sutherland. The images in each cluster cover ~80 per cent of their respective Abell radii. We identified a total number of 1715 galaxies distributed over the six cluster candidates, of which only ~15 per cent were previously known. We study the structures and richnesses of the six clusters out to the cluster-centric completeness radius of r_c_ < 1.5 Mpc and magnitude completeness limit of K^o^_s_ < 15.5^m^, using their iso-density contour maps and radial density profiles. The analysis shows VC04 to be the richest of the six. It is a massive cluster comparable to the Coma and Norma clusters, although its velocity dispersion, {sigma}_v_ = 455 km/s, seems rather low for a rich cluster. VC02 and VC05 are found to be relatively rich clusters while VC08 is rather poor. Also, VC05 has the highest central number density among the six. VC11 is an intermediate cluster that contains two major subclusters while VC10 has a filament-like structure and is likely not to be a cluster after all.2023MNRAS.522.2223Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/522/2223CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/443/41 : Deep NIR photometry of HI galaxies in ZoA (Williams+, 2014)J/MNRAS/396/2367 : NIR Ks photometry of Norma cluster (A3627) (Skelton+, 2009)J/MNRAS/383/445 : Radial velocities in the Norma cluster (A3627) (Woudt+,2008)J/MNRAS/368/534 : Near-infrared study of CIZA J1324.7-5736 (Nagayama+, 2006)J/MNRAS/354/980 : Near-infrared survey around PKS 1343-601 (Nagayama+, 2004)J/MNRAS/305/259 : EFAR galaxies redshifts & velocity dispersionsJ/MNRAS/301/881 : The ROSAT brightest cluster sample - I.
