We present the first observational confirmation for an extended circumstellar dust disk around ε Eri. The observations were obtained with the bolometer array SIMBA at the 15m radio telescope SEST in Chile and measure the dust continuum at 1.2mm. The emission, with a total flux of 21.4mJy and a rms of 2.2mJy/beam, is resolved to a deconvolved size of 27.4" which corresponds to 88AU. No clear indication for a ring-like disk structure is seen, possibly also due to the telescope's large beam width of 24''. Models of the object's spectral energy distribution from IR to mm-wavelengths show that the emission can also be explained by a simple disk model. We further demonstrate the strong influence of noise and propose to be cautious with interpretations of the ring substructure.
