Abstract

We present optical colour-magnitude diagrams for the faint bulge globular clusters Terzan 10, ESO  38 and UKS 1. The giant branches are detected but the horizontal branch is near the observational cutoff for the former two clusters and is not detected in UKS 1. We provide estimates of metallicity, reddening and distance for these clusters, some of these values determined for the first time.
