7 lights in formation, changing positionsWhile star-gazing from the balcony of my apartment, I suddenly saw 7 lights flying in formation at about 2 kilometers (estimated) from the ground. These objects constantly changed positions, were very bright and made absolutely no noise whatshowever, even though they seemed to be moving at a decent speed. Six of them were pretty close to each other, except for one light that was a bit further away. After about 20 seconds they all seemed to gain height, became smaller and eventually disappeared. This sighting was very remarkable and has left me stunned. Shortly after seeing the objects (a few hours) I wrote this report. I also checked recent reports on the NUFORC website and discovered similar sightings that took place in Edmonton, Canada.
