Absolute Proper Motions to [ITAL]B[/ITAL] ∼ 22.5. V. Detection of Sagittarius Dwarf Spheroidal Debris in the Direction of the Galactic Anticenter

We have detected a population of predominantly blue (B-V ≤ 1.1) stars in the direction l = 167°, b = -35° (Kapteyn Selected Area [SA] 71) that cannot be accounted for by standard star count models. Down to V ~ 20 mag, the colors and magnitudes of these stars are …
