| Name | Sydney L |
| Experience Level | 2/5 |
| Remarks | When I first saw it, I didn't know what it was. It was so big and bright that it looked like a firework that someone had set off in the neighborhood I spotted it above. It seemed very low, and it wasn't high enough to have disappeared behind the mountains. I was a passenger in a car, so I didn't hear anything. |
