A big circle and several humain faces in the skyI take several photos for the same view to verify if the big circle on the first photo I send to you was an optical effect or if there is other thing. Later when I review the photos on my digital camera, I found this circle in the clouds and I also notice several human faces in the photo and also in the photo I take just a few seconds before. When I consider the first photo, it's as if the clouds is preparing to show the circle in the second photo (my english is not good enough to explain more precisely).
