The nuclear dependence for 800 GeV/c proton production of J/ψ's has been measured near xF=0. $J/ psi-'s produced from beryllium, carbon, and tungsten targets were detected with the Fermilab E789 pair spectrometer. These data extend the results from E772 down to the range xF=-0.1 to 0.1 and indicate a gradually increasing suppression as xF falls below zero.
