This fireball appeared on the OMMP network on Apr 21, 2023 at 16:29:40 (UTC).
Hadrien first look 2023-07-06:
Relatively weak body.
Dynamics before the last explosion shows that a couple of hundred grams were still present at that point.
Final explosion at ~34.9km (57.2344,20.4318).
One main mass survives beyond that, but burns up pretty quickly after that (~12 km/s).
Unclear if there smaller fragments could have survived from the explosion.
