Reports Report 451ec (Event 451-2015)

Observer
Name S F
Experience Level 3/5
Remarks We observed this fireball from horizon to horizon, which took several minutes, 70 seconds of which was recorded, so we feel we have an accurate idea of time visible. It was by far the brightest object we have seen and left a significant train behind it that glowed for several minutes after the fireball itself was no longer visible. We are very familiar with the location it was observed in so are confident it was traveling almost directly South to North.

Fragmentation
Observation Yes
Remarks One very large fireball with 5-6 significant but smaller trailing fireballs that persisted in excess of 30 seconds of visibility. Main fireball was observed from horizon to horizon. The fragmentation may have been visible earlier, but was noted at the apex of the path and as the fragments began traveling 'down' from the viewer's perspective.
