  The behavior of charmonia after the deconfinement transition is investigated
on quenched lattices. Analysis of temporal correlators on fine lattices at
temperatures upto 3 T_c show that the J/psi and eta_c survive the deconfinement
transition with little significant changes, and survive as bound states at
least upto 2.25 T_c. The spatially excited chi_c states suffer serious system
modifications, maybe dissolution, already a little above T_c.
