Sorry for my bad english i am from brazil. A circle shaped green UFO look-a-like began to fly beyond my backyard when i was doing laundry. when i finished doing laundry, i started hanging the clothes, later, a slowly moving green circle shaped object in the skies began to develop itself as the clouds had just come out. i did quickly get my camera and photographed it (and pointing with my hands to indicate the place ufos were) and the circles began to slowly disintegrate, but not so fast , then it began to return to it normal form. when i tried to warn my family about the ufo, it was too late. unfortunately, the weather was rainy because of the winter period there. This thing can return, if it does, again, i will inform you UFO Hunters guys. Thanks.
