This was the longest amount of time I've ever witnessed a meteor fly across the sky. When I first noticed it it was a bright white and started to change to a brilliant green about halfway through my observation of it. There was a lot of yellow sparks fragmenting from it also. I heard no sonic booms because I was traveling in a car. It's trajectory seemed fairly level across the sky but did appear to drop slightly through it's path and dropped somewhat sharply for a very short distance before it burned out.
