I was playing in a bar with my jazz band. At one point the audience started standing up and pointing at the sky. After a while we stopped playing and went to check it out. When I looked up I saw dozens of lights in a shape almost rectangular. I got shocked and felt some kind of fear of the unknown. My first reaction was to capture it on film, but my cellphone has low quality so it couldn't capture the small lights, then we tried the IPhones, and they still didn't capture it. So we stood there and watched, there were about 30 people on the bar watching it. The formation from my prespective made a rectangule of 5-8 centimeters in the sky, it had a synchronized flux of energy that pulsated down->up. The formation started moving really slow and diagonally from SW to S and then moved up. It slightly changed of shape during its course but maitained a synchronized formation. Then we were asked by the bar's owner to keep playing, so I didn't get to see it disappear. The next day when I went to check my facebook and a friend of my who is also a musician, was playing on another bar in the same town. He had posted " what are these shiny dots in the sky? ", then I realised we could have about 70 witnesses on this event, just in Ferragudo. It was big enough to have been seen from nearby cities.Thanks, [NAME REMOVED]
