We report on the first observation of open charm production in neutral curr
ent deep inelastic neutrino scattering as seen in the NuTeV detector at Fer
milab. The production rate is shown to be consistent with a pure gluon-Z(0)
boson production model, and the observed level of charm production is used
to determine the effective charm mass. As part of our analysis, we also ob
tain a new measurement for the proton-nucleon charm production cross sectio
n at roots = 38.8 GeV.
