Fe Kα flux images of the Sgr A complex in the period 2000–2012. The dotted lines mark the regions discussed in the text and whose light curves are extracted. The bottom right panel shows the same regions, as grey ellipses, compared to the various structures of the molecular complexes traced by CS shown as solid lines (blue −20–10 km s⁻¹, red 10–40 km s⁻¹ and green 40–70 km s⁻¹). Short timescale (≲2 yr) variations are mostly visible in structures in the last velocity range.
