Scientific paper

We detected a faint outburst from a weak Galactic Center transient, during a series of three XMM-Newton observations (~40 ks each) performed on 2009 April 1-5 as part of a multi-wavelength campaign on Sgr A*. The source is located at RA(J2000)=17h 45m 37.97s Dec(J2000)=-29m 00m 23.3s (positional uncertainty of 2.0 arcsec), which is 27 arcsec from Sgr A*. Taking a distance of 8 kpc to the GC places this source at a minimum distance of 1 pc from the supermassive black hole.
