Resumo: We have carried out BVRI and Gunn z CCD photom­ etry for the globular cluster NGC6652 which had no previous colour magnitude study. This cluster, which is projected close to the bulge minor axis at ≈ 11° from the center, has a CMD morphology suggesting a moderately high metallicity of [Fe/H] ≈ -0.9. The Horizontal Branch is red with the possibility of a few members in the RR Lyrae gap. The cluster appears to have several blue stragglers. We derive a reddening of E(B-V) = 0.10 ± 0.02 and a distance of dʘ = 9.3Kpc. The turnoff is reached and we obtain ∆V(TO-HB) = 3.35±0.16 suggesting that it is slightly younger than the average age of Galactic globular clusters.

This cluster, which is projected close to the bulge minor axis at ≈ 11° from the center, has a CMD morphology suggesting a moderately high metallicity of [Fe/H] ≈ -0.9. The Horizontal Branch is red with the possibility of a few members in the RR Lyrae gap. The cluster appears to have several blue stragglers. We derive a reddening of E(B-V) = 0.10 ± 0.02 and a distance of dʘ = 9.3Kpc. The turnoff is reached and we obtain ∆V(TO-HB) = 3.35±0.16 suggesting that it is slightly younger than the average age of Galactic globular clusters.
