A New X-Ray Transient Discovered with XMM
Abstract
A new transient X-ray source in the Galactic Center Region has been discovered with EPIC in a XMM-Newton observation performed on March 12 2003. The position of the source is RA (J2000.0)=17 47 16.0 Dec (J2000.0)=-28 10 45 with an uncertainty of 5 arcsec. The source spectrum can be fit with an absorbed powerlaw with photon index 2.1+/-0.1 and Nh=(8.9 +/- 0.5)x10^22cm-2. The large absorption suggests a source located at the galactic center distance.For a distance of 8 kpc, the source luminosity is about 5x10^34 ergs/s (2-10 keV,corrected for the absorption).
