| Name | Nion D |
| Experience Level | 3/5 |
| Remarks | What caught my attention when I went outside was the colorful prismatic tail more than the glowing white light. I've seen a colorful prism effect in the daytime from both sundogs and rainbows but neither came close to the intensity of the fireball tail. |
