The transient x-ray source XTE J1650-50 discovered with the RXTE ASM
was confirmed with PCA measurements on Sept. 6.39 (0.33 Crab) and
6.62 (0.39 Crab). PCA scans in the second observation give a best
fitting R.A.= 16h50m00s, Decl. = -49o59' (equinox 2000.0) with an
estimated uncertainty of about 2'. The continuum spectrum was a power
law with a photon index of 1.5 and a small amount of a black body with
kT = 1.2 keV, typical of hard states of black hole candidates. No
pulsations were seen.
