It was amazing. I've never seen a "fireball" like this. I've seen shooting stars (meteor showers) and have been to giant telescopes at observatories. This was by far the most exciting thing I've ever seen in the night sky. Bright white with a light green backside and a long tail. It was a little bigger than the size of the eraser of a pencil if you held it out about two feet from your face and the tail from that would be about 3-4 inches long... Amazing! almost scary... but amazing!
