From the analysis of HST-FOC images of the globular cluster 47 Tuc, we have determined the position of the center of gravity to be ∼6″ away from the luminosity center. The luminosity center is mainly determined by an asymmetry in the luminosity distribution of the stars brighter than m342~16.5. The density profile from the dynamical center shows a central cusp with core radius 8″ and significantly deviates from a King profile up to ∼13″ from the center.
