    Abstract

    We present observations at 250, 350 and 500I?m of the nearby galaxy cluster Abell 3112 (z= 0.075) carried out with the Balloon-borne Large Aperture Submillimeter Telescope. Five cluster members are individually detected as bright submillimetre (submm) sources. Their far-infrared spectral energy distributions and optical colours identify them as normal star-forming galaxies of high mass, with globally evolved stellar populations. They all have (B-R) colours of 1.38 A? 0.08, transitional between the blue, active population and the red, evolved galaxies that dominate the cluster core.
