| Name | Mark T |
| Experience Level | 2/5 |
| Remarks | The object was very bright and very clear. I initially thought it was some fireworks, but it was traveling towards earth and had a very distinctive shape and tail. I observed it for a few seconds, but it was very bright and low in the horizon - i believe it may have lasted much longer. |
