Spectroscopic measurements confirm a tight 6D phase-space clump of four RGB stars as part of the distant southern spur of the Sagittarius stream, likely stripped from Sagittarius's halo in the earliest interaction phases.
The Milky Way stellar halo is radially anisotropic inside ~35 kpc and becomes tangentially dominated farther out; after removing known accreted structures the profile stays radially biased at all radii.
