That’s as good a guess as any. If it looked like it was closer, I’d say it’s a bug.
Could be a bat.
Wow, I’ve never experienced recording something like that. I would think a bird or bat would be dark in color, but this is in near infrared, and I have a black coat that reflects infrared so nicely it looks white. So still possible.
My first thought was a reasonably-sized meteor that skimmed the top of the atmosphere, but that would be pretty rare, and it would have to be pretty large to last that long.
So I vote UFO, lol.
P.S. – Anyone watching this jump to the middle of the timeline to see the object.
