Abstract
We present the first results of our X-ray monitoring campaign using the X-ray satellites XMM - Newton and Chandra on the 1.7 square degree region centered on Sgr A*. The purpose of this campaign is to monitor the X-ray behavior of X-ray sources (both persistent and transient ones) which are too faint to be detected by monitoring instruments aboard other satellites currently in orbit (e.g., RXTE , Integral , Swift ). Our first observations were obtained on June 5, 2005, using the HRC-I detector aboard Chandra . Here we briefly discuss our results on the very faint X-ray transients we detected during these observations. We detected new outbursts (with peak luminosities close to $10^{36}$ erg s $^{-1}$ ) of the two very faint transients GRS 1741.9–2853 and XMM J174457-2850.3, as well as a potential new very faint X-ray transient with an outburst luminosity of a few times $10^{34}$ erg s $^{-1}$ .
