  The recently-developed techniques of Noether analysis of the quantum-group
spacetime symmetries of some noncommutative field theories rely on the {\it ad
hoc} introduction of some peculiar auxiliary transformation parameters, which
appear to have no role in the structure of the quantum group. We here show that
it is possible to set up the Noether analysis directly in terms of the
quantum-group symmetry transformations, and we therefore establish more
robustly the attribution of the conserved charges to the symmetries of
interest. We also characterize the concept of "time independence" (as needed
for conserved charges) in a way that is robust enough to be applicable even to
theories with space/time noncommutativity, where it might have appeared that
any characterization of time independence should be vulnerable to changes of
ordering convention.
