Reports Report 2029n (Event 2029-2019)

Observer
Name Domenico R
Experience Level 3/5
Remarks I am aware what meteors are, what they look like, the physics of their balistic entry into the atmosphere, etc. as an aerospace engineer and a teacher. In recent weeks I had taught a lecture to my students about meteors including some of the famous ones, where they can information about them, this website, and more. I've seen some good meteor showers in my life, but this fireball was the most impressive I've ever seen in my life. It seemed to come in at a moderate angle, moved across the sky at an incredible speed, and continued until I couldn't see the leftover fragments against the bright lights of the city as they approached the horizon which had city lights shining, headlights from cars, and tree-covered hills in the area. The 9:05PM reporting time is my best guess; the event was sometime between 9:00PM and 9:15PM.

Terminal flash
Observation Yes
Remarks There was a moment of peak heating when it was its brightest and then dimmed but a small fragment (maybe multiple fragments) faintly glowed and kept going until I couldn't see it any longer. Maybe not so much as an "explosion" as just a few seconds of peak heating and then an abrupt end to that peak heating.
Fragmentation
Observation Yes
Remarks Yes, multiple small bits falling off early in the flight and then maybe a few multiple pieces coming out of the peak heating moment.
