Reports Report 6140l (Event 6140-2019)

Observer
Name Will H
Experience Level 2/5
Remarks I don't want this to be the only fireball I ever see... All told, though, I honestly rate the experience right up next to the level of the total solar eclipse of August 2017 (I saw that at 99.8%, from the Cahokia Mounds site a bit North of St. Louis.)

Remarks The whole experience seemed like a terminal flash, actually, bigger and brighter than any non-lunar object I've ever seen in the night sky in the 40+ years of my lifetime.
Fragmentation
Observation Yes
Remarks The biggest chunk remained traveling in its original direction, and the small extra bit or two skewed slightly downward from that angle toward the horizon below.
