Abstract (from CDS):

We report the discovery of a cold stream near the southern Galactic pole (dubbed as SGP-S) detected in Gaia Early Data Release 3. The stream is at a heliocentric distance of ∼9.5 kpc and spans nearly 58° by 0.°6 on sky. The color-magnitude diagram of SGP-S indicates an old and metal-poor (age ∼12 Gyr, [M/H] ∼ -2.0 dex) stellar population. The stream's surface brightness reaches an exceedingly low level of ΣG ≃ 36.2 mag arcsec–2. Neither extant globular clusters nor other known streams are associated with SGP-S.
