Fragmentation
Observation	Yes
Remarks	It maintained its brightness throughout its trajectory. At the end, it just fizzled out, much as a bottle rocket would. It did not just disappear, though - I had the sense that, for a brief instant, the color briefly shifted (perhaps more to an amber). The trajectory seemed to shift ever-so-slightly upward. It seemed as if there was a tiny amount of fragmentation at the end, though if there was any it was very tightly constrained to the initial radius of the fireball. And last, I had the sense of a very short vapor trail after it disappeared - but the lighting at that time of day made it difficult to say for sure.
