The antiferromagnetic Neél temperature TN is calculated as a function of the Coulomb interaction U for a half-filled 3D Hubbard model. Numerical results are given for the specific heat and staggered magnetic suspectibility on periodic lattices ranging from 43103 sites, and used to determine TN. The size dependence of the results suggests that the transition is weakly first order at small to intermediate values of U.
