| Name | Nate B |
| Experience Level | 2/5 |
| Remarks | The fireball went below the treeline before I saw the end of it, so I don't know if there was an explosion. Tiny tail as it traveled, more like the description of ionization than smoke. Extremely bright, visible in the sky before any stars. Traveling very fast, similar in speed to meteors/shooting stars I've seen but much larger and brighter. |
