As a complement to our photometric studies on southern open clusters (OCs), we present preliminary results obtained from a photometric analysis in the Washington system C and T1 passbands of some poorly known Galactic OCs. The observations were made using the CTIO 0.9m telescope. Basically, we determine linear radii, reddenings, distances and ages of the observed objects. The present results are part of a major project which aims to characterize almost a hundred OCs observed and analyzed in a homogeneous way.
