Multicolour imaging polarimetry of the main sequence star BD+31°643 shows that the Kalas & Jewitt (1997) disc extends to at least 13000AU. A disc of this radius must be dynamically very young compared to the central star, unlike the situation found in the β Pictoris system. A striking linear filament of 850μm emission detected 50″ south, that parallels the dust disk, is probably not physically associated.
