Description: I was on holiday in Florence, Italy, and late morning I took a photo of the River Arno, which flows through the city. I wasn't taking any notice of what was happening in the sky. On my return to England, I transferred my photos onto my computer and printed the one of the River Arno. I was surprised to see that it included a clearly observable `thing` in the sky. I enlarged the photo, and it appears to be a picture of a UFO. source: www.mufon.com
