We present results for charmonium corelators and spectral functions in 2-flavor QCD on anisotropic lattices. We find that the S-waves (J/ψ and ηc) survive up to temperatures close to 2Tc, while the P-waves (χc0 and χc1) melt away below 1.2Tc. We also discuss charm diffusion and charmonium at non-zero momentum.
