Meteorite was of considerable size and was probably the biggest one I've ever seen before. In the north of Waterloo Ontario I was Facing East and it was almost as if it was coming straight at me with a small deviation from south to North. I saw the comet approach from a Southeast Direction and land towards the Northwest as my diagram shows. I was driving at the time so I'm not sure about sounds but it lit up the sky with a green tracer. It was very bright. This happened at approximately 2:35 a.m. I work night shift so I was very awake and attentive.
