Last night (in kitchener ontario) we were looking up at the stars in our back yard. i did see a shooting star earlier but then around 11:15 pm i saw what i will call a wave of lights traveling together. i said to my wofe beside me, "there's something!" they might have been shaped like a large w (they were very dim and barely perceptible, but they were definitely there) and in terms of scale they took up as much sky as a small constellation does (from our perspective). they were very dim, as i said, but i had a second to check my perception, and they were still flying in the same direction for that second or two. they looked like a fleet of lights very high up, traveling in formation, or a very large ship (very large, would have had to have been) very high up in the atmosphere. they traveled toward the north-north-west and faded slowly into obscurity. they seemed to be very high up in the atmosphere, at the height of airplane travel but perhaps ascending higher.
