Multi-wavelength images of the Galactic center in early April 2009. North is to the top, East to the left, and the Galactic plane runs from upper left to bottom right. The sub-mm and X-ray images (left and middle panels) are summed over one or several observations, whereas the L′-band NIR image (right panel) corresponds to the summit of Flare A. Color scales are given in units of Jy beam^-1, counts pixel^-1, and ADU, from left to right, respectively.
