Abstract: We have mapped 1.3 degree2 of the Coma cluster from the core to beyond the NGC 4839 group. Here, we present radial U-band Coma galaxy luminosity functions (LF). The central LF can be represented by a Schechter function, but the radial LFs have very different shapes. We speculate that the derived steepening of the faint end slopes at large cluster radii is indicative of the existence of environmental effects towards the cluster core. The flat faint end slope of the NGC 4839 group supports a scenario in which the group has already passed through the cluster center.
