My dad have noticed a Y-shape light effect over the valley. I've made a few shots of it but unfortunately there's no option for direct upload a pic on this website (gotta use an email) so I have to apologize for my lame English of my explanation.In a matter of fact, as it's written above, the were a Y-shape 2 beams of light convirging to a ground and a light from a bottom.Well, I'm not really sure it was a UFO because the area where the light from bottom was seen is a suburbs of the city of Coimbra so I guess it might be just a weird optical effect because there were heavy clouds.
