The extremal geometries turn out to be completely smooth, with no horizon and no singularity. The solutions have the right charges to be the duals of a family of CFT microstates which are obtained by spectral flow from the NS vacuum.24 pages, 1 figure, LaTeX, References added and a sign convention changedHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
