We report our latest results on charmonium suppression as measured at the CERN-SPS in Pb-Pb interactions at an incident beam momentum of 158 GeV/c per nucleon. Preliminary results obtained from the most recent sample of data collected in year 2000 under improved experimental conditions are compared with published results. For the most peripheral Pb-Pb collisions, J/psi suppression agrees with the normal absorption measured from interactions of lighter nuclei while a steady increasing abnormal supression is observed with increasing centrality.
