In the first work in a projected series aimed at studying the asymptotic regions of the monopole moduli spaces, Kottke and Singer construct a partial compactification of the moduli space of magnetic monopoles in which monopoles of charge k decompose into widely separated "monopole clusters" of lower charge going off to infinity at comparable rates. They cover the Bogomolny equations on a scattering manifold, formal 1-parameter families, moduli of ideal monopoles, universal gluing space and parameterized gluing, and the metric.
