Proper motions with Subaru. II.

We search for stars with proper motions in a set of deep Subaru images, covering about 0.48 square degrees to a depth of i'~=26, taken over a span of five and a half years. We follow the methods described in Richmond et al. (2009, Cat. J/PASJ/61/97) to reduce and analyze this dataset. We present a sample of 69 stars with motions of high significance, and discuss briefly the populations from which they are likely drawn. Based on photometry and motions alone, we expect that 14 of the candidates may be white dwarfs. Our candidate with the largest proper motion is surprisingly faint and likely to prove interesting: its colors and motions suggest that it might be an M dwarf moving at over 500km/s or an L dwarf in the halo.
