Abstract (from CDS):

On September 17, 2003 INTEGRAL discovered a bright transient source 3.° from the Galactic Center, IGR J17544-2619. The field containing the transient was observed by XMM-Newton on March 17 and September 11 and 17, 2003. A bright source, at a position consistent with the INTEGRAL location, was detected by the European Photon Imaging Camera (EPIC) during both September observations with mean 0.5-10keV unabsorbed luminosities of 1.1x1035 and 5.7x1035erg/s for an (assumed) distance of 8kpc. The source was not detected in March 2003, with a 0.5-10keV luminosity of <3.8x1032erg/s. The September 11 and 17 EPIC spectra can be represented by a power-law model with photon indices of 2.25±0.15 and 1.42±0.09, respectively. Thus, the 0.5-10keV spectrum hardens with increasing intensity. The low-energy absorption during both September observations is comparable to the interstellar value. The X-ray lightcurves for both September observations show energy dependent flaring which may be modeled by changes in either low-energy absorption or power-law index.
