The old open clusters Saurer A, B and C revisited.

CARRARO G. and BAUME G.

Abstract (from CDS):

We report deep (V ~ 24.0) VI CCD photometry of three fields centred in the regions of the old open clusters Saurer A, B and C. In the case of Saurer A, which is considered one of the oldest known open clusters, we also provide a comparison field. From the analysis of the photometry we claim that Saurer A is as old as M67 (~5 Gyr), but more metal-poor (Z 0.008). Moreover, it turns out to be the open cluster with the largest galactocentric distance so far detected.
