I was sitting in the yard, at 4 Pm with a friend; then I saw a (starlike) light moving very quickly across the sky, it took 3 or 4 minutes to cross all over the sky. I though it was a Firefly, but it was moving very fast, and was very far. Immediatly we saw another one, with the same characteristics. From 4 Pm to 4:15 Pm, we have seen 6 UFO. Then there was no activity. But it reappears at 4:40 Pm, and we saw others 4 UFO, until 5 Pm, because the sun started to rise.The object moved straight to the horizon, with some little variations and direction changes.I was fascinated watching the speed of these UFOs. I lost the sight in the horizon, and seems like the object were fading off.
