The structure is probably the remnant of a now fully disrupted globular cluster, lies $\\approx 3.8 \\, {\\rm kpc}$ away from the Sun in the direction of the Galactic bulge, and possesses highly retrograde motion. We find that the system orbits close to the Galactic plane at Galactocentric distances between $4.9$ and $19.8 \\, {\\rm kpc}$.
