Caption: Figure 9.

Left: a newly detected object (m ∼ 20.5), not previously reported in the DEEP catalog, is barely noticeable in the average image. Based on its apparent motion, it is consistent with a main-belt asteroid. Middle: the motion-filtered image enhances its trail, and YOSO flags a segment of it as n2756. Right: the shift-and-stack refinement converges to a precise apparent motion, of ﹩(\dot{\alpha },\dot{\delta })\approx (-26\mathop{.}\limits^{\unicode{x02033}}00,-10\mathop{.}\limits^{\unicode{x02033}}42)﹩ hr−1, corresponding to a total sky-plane motion of ∼28″ hr−1.
