| Experience Level | 3/5 |
| Remarks | Never seen a trail or meteor last that long, going from the top of the sky almost all the way down to the ground. No sound heard, but it was far off. Large white trail, very large. The fireball was white, with light green and blue at the bottom of the ball. Lasted longer than most other fireballs I've seen previously. |
