We present a study of charmonia in hot gluonic plasma, for temperatures up to three times the deconfinement transition temperature ${T}_{c}.$ $q\overline{q}$ systems with quark masses close to the charm mass and different spin-parity quantum numbers were studied on very fine isotropic lattices. The analysis of temporal correlators, and spectral functions constructed from them, shows that the $J/\ensuremath{\psi}$ and ${\ensuremath{\eta}}_{c}$ survive up to quite high temperatures, with little observable change up to ${1.5T}_{c},$ and then gradually weaken and disappear by ${3T}_{c}.$ For the scalar and axial vector channels, serious modifications are induced by the hot medium already close to ${T}_{c},$ possibly dissociating the mesons by ${1.1T}_{c}.$
