  We construct a set of supersymmetric geometries that represent regular
microstates of the D1-D5-P 3-charge system, using the solution generating
technique of hep-th/0311092. These solutions are constructed as perturbations
around the maximally rotating D1-D5 solution at the linear order, and depend on
the coordinate of S^1 on which the D1- and D5-branes are wrapped. In the
framework of six-dimensional supergravity developed by Gutowski, Martelli and
Reall [hep-th/0306235], these solutions have a 4-dimensional base that depend
on the S^1 coordinate v. The v-dependent base is expected of the superstratum
solutions which are parametrized by arbitrary surfaces, and these solutions
give a modest step toward their explicit construction.
