This light curve of the 6.4 keV line emission from neutral iron in the Sgr B2 region is composed from archive data of four X-ray missions:
| September 1994 | ASCA (Japan) |
| March 2000 | Chandra (NASA) |
| April 2001 | XMM-Newton (ESA) |
| July 2001 | Chandra (NASA) |
| September 2004 | XMM-Newton (ESA) |
| October 2005 | Suzaku (Japan) |
The Sgr B2 region for which the combined light curve was derived by Tatsuya Inui et al. [2008] is outlined in the related image.
Two prominent objects in this region, M0.66-0.02 and G0570-0.018, show a similar light curve over the studied period. From the combined X-ray data Tatsuya Inui et al. [2008] arrive at the conclusion that Sgr A*, the black hole at the Galactic centre, caused X-ray fluorecense in these two objects some 300 years after Sgr A* experienced an outburst.
