Fe Kα flux mosaics smoothed to 9 arcsec. (Red) Chandra data from 1999 to 2003 (only observation 3392 has been kept among 2002 observations); (green) Mosaic map from 2004 to 2007; (blue) Mosaic map from 2008 to 2011. The emission has been strongly varying in the Sgr A complex with a clear trend from west to east in MC1 and MC2, a late illumination of Br1 and Br2, and more complex variations in G0.11-0.11. We assume Br2 emission is only associated with the blue patch at the center of the region, the rest being mostly due to the underlying G0.11-0.11 cloud.
