We report the discovery of a new ultra-faint Milky Way satellite candidate, Horologium II (Hor II), detected in the Dark Energy Survey Y1A1 public data. Hor II features a half-light radius of r h = 47 ± 10 ?> pc and a total luminosity of M V = − 2.6 − 0.3 + 0.2 ?> that place it in the realm of ultra-faint dwarf galaxies on the size–luminosity plane. The stellar population of the new satellite is consistent with an old (∼13.5 Gyr) and metal-poor ([Fe/H] ∼ − 2.1 ?> ) isochrone at a distance…
