Abstract (from CDS):

We report the discovery of a narrow stellar stream crossing the constellations of Sculptor and Fornax in the Southern celestial hemisphere. The portion of the stream detected in the Data Release 1 photometry of the ATLAS survey is at least 12° long, while its width is ~0 _.^○25. The colour-magnitude diagram of this halo sub-structure is consistent with a metal-poor [Fe/H] ≲ -1.4 stellar population located at a heliocentric distance of 20±2 kpc. There are three globular clusters that could tentatively be associated with the stream: NGC 7006, NGC 7078 (M15) and Pyxis, but NGC 7006 and 7078 seem to have proper motions incompatible with the stream orbit.
