| Name | Briana N |
| Experience Level | 3/5 |
| Remarks | The fireball didn't look as big as the moon, but was big enough to look like a softball burning across the sky. It was way brighter than any shooting star I've seen. It lasted long enough for me to get the attention of people around me and for them to look up and observe it and gasp. We were at a county fair and it is well lit at night, but it still was brilliant. |
