The 12th of september 2003 i was talking photos of a beautiful sunset over big clouds at the east of Cancun, Mexico. My appartment that time was in cancun downtown and the view of this clouds from the balcony was not so spectacular, so to get better photos i went to the middle of the avenue infront. There i stood for about 5 minutes and took 19 shots with my Sony digital camera DSC-P71 3.2Mpx. Some minutes later, at home, i downloaded the photos to my computer a try to choose one to use as a screensaver. In two of the photos (No. 15 and 16) i saw something unusual. When i zoomed the image No.16 i saw of what it appeared to be a metallic sphere, still today i don���t know what this can be, in photo 17 taken some seconds later the object is gone. And in photo 15 (top right) there is a small dark object moving, don���t know if it���s the same sphere.I hope that somebody can help me determine what is there in the photos.
