Reports Report 3210cc (Event 3210-2017)

Observer
Name Jacob D
Experience Level 2/5
Remarks I have watched meteor showers since I was a kid, and I've never seen such a bright and long streak across the sky. Drove 20 min to a secluded parking lot on a whim with my gf to stargaze because the area showed low light pollution. No sooner were we about to leave did this thing come out of nowhere! It got both our hearts going as we were unsure of what exactly it was. Quite an experience.

Duration 3s
Length 20°
Remarks Extremely thick train, say 1/3rd of moon size (relatively) for first 50% of train. Very bright, glowing yellow/white/green color. Train thinned out as fireball progressed past 50%. Solid connected train until last 5% of path where the train became spotty.
Terminal flash

Remarks Pulsing bursts of bright light. Initial entry flare was extremely bright, whiting everything else in field of sight out. 3-4 more flashes of similar brightness incurred in first 20% of train. Then a constant brightness for the next 50%. Then dwindling brightness. Initial pulses and continuous flare for 70% of path was very bright.
Fragmentation
