Several Midwestern Ontario residents saw a bright flash of light Tuesday evening out over Lake Huron.
The object was also seen in many parts of Michigan, and is reported to have been quite loud.
Postings online indicate the point of impact was near metro Detroit. Some people reported their windows rattled.
The U-S National Weather Service in Detroit said in a Twitter post that it was likely a meteor.
Kalamazoo Astronomical Society president Richard Bell says it was likely a meteoroid, or a small chunk of rock or metal entering the atmosphere.
