A friend and i went to the official opening of an ecopark called S���ijil Noh H��� inside a forestal reserve called Much��� Kanan Ka���ax in the state of Quintana Roo, Mexico.. about 135 miles south of the city of Cancun. We went there and spent some 4 hours. We took a boat tour around the lake and took pictures of the magnificent landscape, of course we took pictures of our captain. Later, while checking the photos my friend noticed something in some of the pictures i took with my camera (lumix 10 Mpx). It appears to be a sphere above the forest but no to far from where we were. I must say that in the opening event there were no balloons thrown to the sky. The object was not visible with naked eye only on camera. This is the second time it happens to me to photograph a sphere in this zone of mexico, the firt report is thi one (http://mufoncms.com/cgi-bin/manage_sighting_reports.pl?mode=view_long_desc&id=16319&rnd=935531247690778)
