The data accumulated in the Photographic Archive of the UBAI were used. The total number of processed plates is 1963. Astronegatives were digitized with Epson Expression 10000XL scanners in the 1200 dpi scanning mode. The majority of plates have a size of 30x30cm. The catalog contains the data on 13 413 268 stars and galaxies with B≤17.5m at the epoch of 1984.97. The coordinates of stars and galaxies were obtained in the Tycho-2 reference system, and B-magnitudes were determined in the system of photoelectric standards. The mean internal errors of the catalog are σRA,DE=0.23" and σB=0.15mag for all objects or σRA,DE=0.085" and σB=0.054mag for the objects in the B=7-14mag range. The convergence between the catalog and Tycho-2 is characterized by the following values: 0.042" and 0.16m. The mean-square difference in coordinates from the catalog and from UCAC-4 is σRA,DE=0.26" (9 892 697 objects, or 73.75% of stars and galaxies, were identified). Description: The catalog of positions and B-magnitudes of near 13.4 million objects (FONAC-S) is presented. The catalog is a result of digitizing, image processing, and reduction of 1963 photographic plates of FON observational project from Kitab Observatory of Uzbekistan glass archive. File Summary:
