| Fragmentation | |
|---|---|
| Observation | Yes |
| Remarks | The fireball didn't really get brighter as it neared the horizon, but it did appear to split into two. At that point, it began to travel much faster and disappeared behind some trees. Before the point that it split in two, the fireball traveled very slowly, almost hovering. |
