This is my photo shop representation of what I saw.
The front end was a lot, lot brighter than I can represent.
The green and a few white sparkles were a lot, lot brighter also.
Seeing it dynamically moving, the sparkles would burn out and constantly be refreshed by new ones, kind of like a fireworks sparkler.
Would have thought the sparkle trail would have had more of a slant to it because of speed, but it didn't, struck me as kind of odd, but I have never seen one with this much detail.
This happened in April of last year.
I guess I observed it for 10 seconds and lost it when a tree was in the way.
No sound or boom, didn't see the final outcome because of the tree.
Even made a thread about it.
