Galactic open clusters are excellent laboratories to study stellar populations that are coeval and have a common chemical composition. These clusters allow for the investigation of stellar and chemical abundance evolution, binary star systems, mass and luminosity functions, Galactic metallicity gradient, and disk structure, among other things. The Southern Open Cluster Study (socs) is a database of a select set of 24 open clusters with a broad range of ages and metallicities. It is an extension of the northern WIYN Open Cluster Study (wocs). The main goal of both studies is to obtain comprehensive photometric, spectroscopic, and astrometric information of these key open clusters. Here, we provide an overview of the socs survey and present results of the wide-field photometry on two socs clusters, NGC 3532 and Tombaugh 2.
