B and V photometry of the metal-rich bulge globular cluster NGC 6304

We present B and V photometry of the bulge globular cluster NGC 6304. We de rive a reddening E(B-V) approximate to 0.5 and a distance from the Sun d(ci rcle dot) approximate to 6 kpc. From the red giant branch morphology we est imate that the metallicity of NGC 6304 is intermediate between those of 47 Tuc and NGC 6528. The cluster is foreground to the bulk of the bulge population and the redde nings are comparable. Evidence of a hot stellar component belonging to the cluster is found. Thes e hot stars could correspond to a blue extended horizontal branch and/or bl ue stragglers.
