We present numerical and analytical calculations designed to assess the viability of a Galactic magnetic monopole halo. The dynamical interplay between magnetic currents and the Galactic magnetic field is treated self-consistently, taking full account of the temporal evolution of currents and fields. We find that in general self-consistent bounds on the Galactic magnetic monopole flux based on the survival of the Galactic magnetic field are far less restrictive than the Parker limit. Our halo models are consistent with monopole masses m/sub M/< or approx. =7 x 10/sup 19/ GeV, and monopole fluxes in the range F/sub M/> or approx. =3 x 10/sup -13/ cm/sup -1/ s/sup -1/. Topics for future, more detailed studies are enumerated and discussed.
