| Experience Level | 4/5 |
| Remarks | I taught astronomy for over a decade, and never saw footage of such a phenomenal fireball display as this. They were bright white, moving very slowly, were low in the sky and traveling completely horizontally in a straight line in many fragments. There was no sound associated with the fireballs, and they did not fade but kept their brightness. |
