Description:
We present optical colour-magnitude diagrams for the faint bulge
globular clusters Terzan 10, ESO456-SC38 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.
