Query: Open Charm as a Probe of Pre-Equilibrium Dynamics in Nuclear Collisions?   The pre-equilibrium contribution to open charm production in nuclear
collisions at $\sqrt{s}=200$ AGeV is calculated using three different models
for the correlations between momentum and space-time coordinates. Ideal
(Bjorken) correlation between the rapidity $y$ and space-time rapidity $\eta$
of mini-jet gluons suppresses greatly the pre-equilibrium yield and even
allowing for the minimal uncertainty correlations leads, in contrast to
previous estimates, only to a small pre-equilibrium charm yield as compared to
initial yield due to gluon fusion. The ``intrinsic'' charm process is
negligible in the mid-rapidity domain.
