| Abstract: |
The USNO CCD Astrograph Catalog (UCAC) project is a high precision, astrometric survey. Observations started in January 1998 at Cerro Tololo (CTIO). A preliminary catalog of 30 million stars has been prepared, covering most of the area between declinations -90 and -15. It has a 10 fold improvement in accuracy over the Guide Star Catalogue (GSC) and a larger density, reaching to 16th magnitude. The catalog is supplemented by preliminary proper motions. |
