We report first results for spectral functions of charmonium in 2-flavour QCD. The spectral functions are
determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/ and c are found to
survive well into the deconfined phase before melting away at T 2Tc. Current systematic uncertainties prevent
us from drawing any definite conclusions at this stage.

nances above the deconfinement transition is a
