| Fragmentation | |
|---|---|
| Observation | Yes |
| Remarks | There were at least two fragmentations before termination, maybe as many as four. Each one looked like one would expect if fiery pieces broke off, leaving very short trails. There seemed to be a bit of fragmentation at the very end, which was far to the ESE, after starting as a very bright (-7?) spot almost due W. |
