Reports Report 4572a (Event 4572-2017)

Observer
Name Ethan N
Experience Level 2/5
Remarks It seemed large, which makes me think it could have been something else. It was probably half the size of a full moon, in terms of degrees covered. Please keep me updated if it turns out to be real! I can't believe my eyes.

Fragmentation
Observation Yes
Remarks Yellow sparks breaking off from the white/green head. Not really true fragmentation (similarly sized objects splitting and following the same rough trajectory). This is what makes me think it could have been a firework, but the angle, brightness, and speed were so different from anything I've ever seen before that I thought it might be real.
