Astrometric Projects at the Bordeaux CCD Meridian Circle

We started in 1997 the astrometric project of re-measurement of the Bordeaux Carte du Ciel zone with our automated CCD meridian circle. These recent observations should be combined with the Carte du Ciel plate measurements scanned at APM (Cambridge) in order to produce an astrometric catalogue of accurate positions and proper motions for all stars detected on the plates. The positions derived from the meridian observations improved the faint part of Tycho-2 positions in this region.
