URAT1 is an observational, astrometric catalog covering most of the δ  −15°area and a magnitude range of about R = 3-18.5. Accurate positions (typically 10-30 mas standard error) are given for over 228 million objects at a mean epoch around 2013.5. For the over 188 million objects matched with the Two Micron All Sky Survey (2MASS) point-source catalog proper motions (typically 5-7 masyr -1 standard errors) are provided. These data are supplemented by 2MASS and AAVSO Photometric All-Sky Survey (APASS) photometry. Observations, reductions, and catalog construction are described, together with results from external data verifications. The catalog data are served by CDS, Starsbourg (I/329).

The results of 4,747 intensified CCD observations of double stars, made with the 26-inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system represents a combination of over two thousand short-exposure images. These observations are averaged into 2,667 mean relative positions and range in separation from 0.′′ 328 to 95. ′′ 9, with a median separation of 8.′′ 673. Four orbits are improved. This is the 22 nd in this series of papers and covers the period 4
