XTE J0929-314: a faint X-ray transient The RXTE All-Sky Monitor has detected a faint X-ray transient at R.A. = 09h29m22s, Decl. = -31 22'.8 (equinox J2000.0; estimated 3' uncertainty at 90% confidence). The source is visible in sky maps computed from 6-day intervals of ASM data. The average flux (2-12 keV) was 15 +- 2 mCrab during 2002 April 13-18, inclusive, rising to 20 +- 2 mCrab (April 19-24), and 26 +- 1 mCrab (April 25-30). The error circle does not contain any noteworthy sources in the Simbad catalogs. The ASM hardness ratios suggest an X-ray spectrum similar to transients associated with weakly magnetic neutron stars or some black hole systems. We encourage optical and radio observations of this new transient.
