The CLEO collaboration proposes to explore the charm sector starting early 2003. It is foreseen to collect on the order of 6 million DD{top}- pairs, 300000 D{sub}S(D{top}-){sub}S pairs at threshold and one billion J/Ψ decays. High precision charm data will enable us to validate upcoming Lattice QCD calculations that are expected to produce 1-3% errors for some non-perturbative QCD quantities. These can then be used to improve the accuracy of CKM elements. The radiative J/Ψ decays will be the first high statistics data set well suited for meson spectroscopy between 1600 and 3000 MeV.
