I was driving while I saw this. I am not sure what is was. It was at least the size of a softball- very bright white with a train of sparks- blueish in color. It seems to pass right in front of my car then disappear. My 12 year old son saw it as well. It was spectacular- I am not sure what it was, but significant enough to take the time to document it.
