Scientific paper

The 4th and final release of the USNO CCD Astrograph Catalog (UCAC4) is upcoming. Shortcomings with the previous UCAC3 release have been resolved and Northern Proper Motion (NPM) data are now available to provide accurate proper motions for UCAC stars all-sky without any Schmidt data. Corrections for systematic positional errors have been updated again and the UCAC4 system is now close to that of UCAC2. External comparisons of UCAC4 data will be presented as well as radio-optical position differences of a sample of ICRF extragalactic sources. UCAC4 will be the basis for the input catalog of the funded JMAPS space mission. The public release of UCAC4 will also be supplemented by all bright stars not observed by the UCAC astrograph using Hipparcos and Tycho-2 data to provide a complete, all-sky catalog to about R=16 mag. Photometry from 2MASS and APASS will be included in the UCAC4 release.
