FAUST Observations of Ultraviolet Sources toward the Virgo Cluster
We analyze three UV images covering a ~100 square degree field towardthe Virgo cluster, obtained by the FAUST space experiment. We detect 191sources to a signal-to-noise ratio of 4.4 and identify 94% of them. Mostsources have optical counterparts in existing catalogs, and about halfare identified as galaxies. Some sources with no listed counterpart wereobserved at the Wise Observatory. We present the results oflow-resolution visible spectrophotometry and discuss the foreground 101stellar sources and the 76 detected galaxies, both in the cluster and inthe foreground or background. We derive conclusions on star formationproperties of galaxies and on the total UV flux from discrete anddiffuse sources in the cluster. We test for the presence of intraclusterdust, determine the clustering properties of UV emitting galaxies, andderive the UV luminosity function of Virgo galaxies.

A catalog of far-ultraviolet point sources detected with the fast FAUST Telescope on ATLAS-1
We list the photometric measurements of point sources made by the FarUltraviolet Space Telescope (FAUST) when it flew on the ATLAS-1 spaceshuttle mission. The list contains 4698 Galactic and extragalacticobjects detected in 22 wide-field images of the sky. At the locationssurveyed, this catalog reaches a limiting magnitude approximately afactor of 10 fainter than the previous UV all-sky survey, TDl. Thecatalog limit is approximately 1 x 10-14 ergs A sq cm/s,although it is not complete to this level. We list for each object theposition, FUV flux, the error in flux, and where possible anidentification from catalogs of nearby stars and galaxies. Thesecatalogs include the Michigan HD (MHD) and HD, SAO, the HIPPARCOS InputCatalog, the Position and Proper Motion Catalog, the TD1 Catalog, theMcCook and Sion Catalog of white dwarfs, and the RC3 Catalog ofGalaxies. We identify 2239 FAUST sources with objects in the stellarcatalogs and 172 with galaxies in the RC3 catalog. We estimate thenumber of sources with incorrect identifications to be less than 2%.

Photoelectric UVBY beta photometry of 230 stars brighter than m(pg) = 13.0 in the two B = +75 deg fields SA 80 and SA 81
The study presents uvby and beta photometry for 123 and 107 stars in SA80 and SA 81 brighter than m(pg) = 13 and earlier than G1. Most starsseem to be of type A or F with sample limits V is not greater than 12.6and beta is not less than 2.60. SA 80 and SA 81 have 34 and 27 BD starsin common with a general b is not less than 70 deg program,respectively. uvby photometry for 19 and 12 stars fainter than m(pg) =13 is also presented. If situated on the standard line, the sample ofabsolutely less luminous F9-G0 stars are complete in the volume confinedto the distance range from 80 to 300-400 pc. Several lines of sight haveE(b-y) exceeding 0.050 m. In both areas the remote A stars seem to bevirtually unreddened or are perhaps bluer than typical for population Istars. SA 80 covers part of the Virgo cluster, and the data may be usedto estimate the galactic reddening in this direction.
