Abstract We present the first results of an investigation into ongoing star formation within E and S0 galaxies, selected from optical catalogs to be on the red sequence. Star formation in these spheroidal systems is traced using ultraviolet imaging from GALEX. We have identified a wide variety of unanticipated sites of apparent star formation in this sample, which include clumps, rings, and other structures. In order to quantify the contributions of these structures to the total UV flux, we have fit Sersic and/or exponential disk profiles to a subsample of 500 galaxies with high S/N, and compared the residuals of these smooth component fits to the original galaxy.
