Commission 8: Astrometry [PDF]
Proceedings of the International Astronomical Union, 2005 AbstractThis triennial report from Commission 8 covers astrometry-related matters for objects ranging from Solar system bodies out to Milky Way stars and QSOs at cosmological distances. This enormous range of distances is needed to establish, maintain, and improve the metric of the visible Universe--a very challenging effort since everything is moving.
