Two images at 8.6   μm, reconstructed from subsets of the May 2007 data. Each image is based on a different set of 4000 frames, corresponding to an on-source integration time of 80 s during an interval of about 19 min. The location of Sgr A* is marked by a red cross. The apparent variability of some of the extended features is caused by the low S/N of these images. The contours are as in Fig. 2.
