This picture was taken very early afternoon (between noon and 1pm on February 22, 2006) on a Sony DCR-PC120E PAL (video/photo combination Handycam.) It was a cold, cloudy day, and the clouds obscurred the sun. The picture before and after did not contain anything strange. You can find the rest of the story at the bottom (source).
Look closely at the form in the middle of the isle.
