We present preliminary results obtained from the photometric study offour galactic open clusters (OCs) with little known characteristics. Theobservations were made with the and filters of the Washingtonphotometric system, using the 0.9 m telescope of the Cerro TololoInter-American Observatory (Chile). The results include thedetermination of some astrophysical parameters of the studied clustersand represent the continuation of a systematic study that is beingcarried out at the Astronomical Observatory of Córdoba. Thisstudy is part of a larger project that aims at characterising almost onehundred galactic OCs observed in the Washington system, which are beinganalysed in a similar way. In some cases, discrepancies are foundbetween the present results and those inferred from photometric dataobtained in the near-infrared spectral region.
