Abstract
We examine the Toda frame formulation of the SO(3)-invariant hyper-Kah ler 4-metrics, namely Eguchi-Hanson, Taub-NUT and Atiyah-Hitchin. Our method exploits the presence of a rotational SO(a)isometry, leading to the explicit construction of all three complex structures as a single t plus a doublet. The Atiyah-Hitchin metric on the moduli space of BPS SU(2) monopoles with magnetic charge 2 is purely rotational.
