A false-color composite of DSSII IR (red), 2MASS KS (green), and our SofI KS image (blue) with ~3.5 × 3 arcmin field of view, centered at WISE J0720. North is up and east is to the left. Another HPM star 2MASS J07200708−0845589, not related to WISE J0720, is visible to the northeast of WISE J0720. The bright green dots on the western side, with no counterparts in the other images, are cross-talk artifacts in the 2MASS. The white dots show the positions of the two HPM stars in 50 yr steps, over a −50−150 yr period, with respect to the DSS2 IR epoch (see Table 5).
