We request WF/PC time to image at high resolution the members of the rich southern cluster AC 114 at z=0.31 which we have studied extensively at the AAT using both fiber-optic spectroscopy and multi-colour photometry. Our comprehensive ground-based data has allowed us to measure precise line indices and colours for individual galaxies in this cluster and, along with data on other distant clusters, to construct a unifying picture for the various phenomena associated with the Butcher-Oemler effect whereby different galaxies are seen at different stages of star-formation activity within a simple cycle. The WF/PC data will allow us to morphologically classify galaxies at various stages in this cycle and resolve many of the questions left unanswered by the ground based data. The AAT catalogue is the largest, most complete spectroscopic and photometric data set where, by virtue of the moderate redshift, detailed information is available for all galaxies to a fixed magnitude limit. As such, our sample forms the ideal first target for HST studies of the evolution of galaxies in dense environments.
