Picture i took the other night from my balcony at 8:00pm, tuesday november the 24th. it was 5 shadow lights, one in the middle and four going from the centre to a certain distance outside together, "synchronisé", and then turning aroud of the middle light and going to the center and then outside. i check this phenomen during one hour and i went inside. an hour later i went back outside, around 22:00pm nothing in the sky. i knew somebody seing the same thing at the end of septempber, she was living on the south shore of montreal, and she wathed with neighbors the same phenomen. but this time, 3 helicopters arrived and went under the lights and stayed there. after an hour and the half, my friend was tired watching it and went inside of her place. here when i check this, i look around if i can see a projector from the ground to the sky, but nothing and the effect was the light came on the other side of the clouds, in the back of it. i took 5 pictures and only one has a picture, the other ones was completely blackout, nothing.
