The radio source PKS 2155-304 has been the subject of substantial study since its discovery as an X-ray source and subsequent identification as a BL Lac object; this interest has been further increased with the discovery by Canizares and Kruper of an absorption trough in the X-ray spectrum. The authors have carried out extensive optical observations of this object. They find from spectra of the associated nebulosity a redshift of 0.117±0.002. Given a knowledge of the redshift, the range of mechanisms which can produce the X-ray trough can be substantially reduced.
