XTE J1650-500

C. Markwardt, J. Swank, and E. Smith, GSFC, report on behalf of the RXTE team at GSFC: "The transient x-ray source XTE J1650-500 discovered with the RXTE ASM was confirmed with PCA measurements on Sept. 6.39 (0.33 Crab) and 6.62 UT (0.39 Crab). PCA scans in the second observation give a best fitting R.A. = 16h50m00s, Decl. = -49o59' (equinox 2000.0; estimated uncertainty about 2'). The continuum spectrum was a power law with a photon index of 1.5, plus a blackbody with temperature kT = 1.2 keV (about 10 percent of total), which is typical of hard states of black-hole candidates. No pulsations were seen."
