Reports Report 2669d (Event 2669-2016)

Observer
Name Katie G
Experience Level 4/5
Remarks I really hope this doesn't discredit everything else I've said... And I believe that this was associated with a UFO. I noticed the UFO before the fireball. It passed over me two different times, then was hovering in this one spot, and then I saw the flameball explode right over it. The UFO stayed for a moment after, and then flew off even faster than when it was flying before. the UFO showed back up, stopped moving again, almost disappeared but there was still a little light, dropped even FASTER than after the flameball, and about 5 seconds after that is when I heard the boom. The UFO dropped (I think it actually landed... That's why I'm freaked out honestly) in the same place I heard the boom come from.

Remarks My mind was pretty blown when I saw it, so I may have lost track of time (and my phone had died, so no time keeper was available), but it was quite awhile after I saw the fireball there was a boom that wasn't so loud that it hurt my ears or anything, but it was massive, like earth shaking I want to say, and sounded like it was coming from where I last saw the fireball where the light had been the brightest

Remarks -
Terminal flash
Observation Yes
Remarks There was a bright, light blue/light green light in the air, like a shooting star except MUCH brighter (and blue/green...) and bigger, and the trail stayed (at least while it was going.. I'm not sure if it stayed once it the ball was done or not), and at the end of it it was like something exploded except it just looked like a really huge, super bright star. Like the North Star, except bright green. I'm actually pretty freaked out about it still.
Fragmentation
Observation Unknown
