CCD PHOTOMETRY OF THE FAINT OLD OPEN CLUSTERS ESO-96-SC04 AND ESO-92-SC18

We present deep CCD BV photometry in the central region of the faint o pen clusters ESO 96-SC04 and ESO 92-SC18. The color magnitude diagrams (CMD) here presented allows us to evaluate the clusters ages. We foun d an age of 5.0 . 10(9) yr for ESO 92-SC18 and 0.7 bullet>10(9) yr for ESO 96-SC04 on the Padova isochrones scale. Estimates of the reddenin g are given for both the target clusters and the distances of these ob jects are substantially revised. We conclude that these clusters belon g to the old tail of the thin disk population, they are among the most distant known open clusters from the Sun and lie near the solar circl e like the majority of the open clusters.
