Everything Under The Sun

I got really lucky and captured what I believe to be a meteor explosion with a resulting, expanding shock wave or debris ring.

UPDATE: After being fortunate to have Universe Today cross post my vid, I learned more about the phenomena recorded here. While this does show a meteor breaking apart, the resulting, expanding ring is called a "persistent train" and is NOT a debris ring. Rather, it is glowing gas - charged gas that has been heated by compression caused by the meteor and giving off electrons (similar to how a neon sign works). It happens fairly often but it isn't so regularly documented.

Because I shoot at much higher resolution than 720p, I was able to provide (2) sequences in this video: (1) is with the full frame of each capture scaled/reduced and then cropped down to 1280x720, and (2) the other is with the full frame kept at resolution with just the region around the explosion cropped to 1280x720. I included each sequence twice - once at 24fps and the other at around 12fps.

Stats for this timelapse sequence:

Exposure: 20sec
Iso: 800
