Fig. 13

Disk passage 3σ contour of J1644 using the Tillich et al. (2011) proper motion as in Fig. 9 (upper right) and for uncertainties σμ reduced from 2.0 mas yr-1 to 0.1 mas yr-1. The latter is expected to be the Gaia end-of-mission accuracy. The black dot marks the GC, the star the current position of J1644, and the solar symbol the position of the Sun.
