Caption: The Moon imaged in the L band (3.45 micron) with SIRCA . A total of 4000 mid-IR images on 500 different positions were obtained with a seeing of 0.3-0.4 arcsec FWHM on July 19th 2003, spending a total of 26 minutes on the observations. Substantially more time was spent making this final mosaic. The authors have also made a very nice interactive SIRCA Moonmap. A browser with Macromedia flash 6 is required.
