Scientific paper

A deep INTEGRAL mosaic of the Norma region centered on PSR J1617-5055 combining IBIS ISGRI data collected over the period March 2, 2003 - Feb. 24, 2006 (INTEGRAL Revolutions 46-411) revealed a new hard X-ray source. We name this source IGR J16293-4603, at R.A. = 16 29 21.4 and Dec = -46 03 50 (J2000). The 3 sigma uncertainty on this position is about 3 arcmin. Fitting the 20-300 keV time averaged flux measurements with a power-law model gives a 20-70 keV flux of (1.12 +/-0.14 )E-11 erg/cm2/s and a photon index of 1.85 +/- 0.30.
