LETTER TO THE EDITOR

We generalize the classification of all supersymmetric solutions of pure N = 2, D = 4 gauged supergravity to the case when external sources are included. It is shown that the source must be an electrically charged dust. We give a particular solution to the resulting equations that describes a Gödel-type universe preserving one quarter of the supersymmetries.
