We cross match the catalog of nearby clusters of De Propris et al. (2003) with the GALEX archive, to search for clusters with sufficient exposure, in far and near UV, to derive the composite luminosity function at 1500 and 2500 Angstroms. We find 20 such clusters in the database (more will come when the 1/2-sky MIS survey is complete). However, when we match the detections with the SuperCosmos and 2dF databases, we find that several UV bright objects are faint enough to have no detection in the photographic plates and that many of these objects have no redshift. This suggests that, if these objects are cluster members, the majority of the star-forming population in clusters is of low luminosity. We are now exploring statistical subtraction and multi-object spectroscopy for a UV selected sample.
