Does this help at all? The line on the left is when the object first becomes visible in the video, and the line on the right is when it explodes and disappears from view - it's actually pretty similar to what you had already.
I happened to be up watching the Super Bowl in the UK, saw the ESA tweet across my timeline and was able to pop outside to see it at the time they predicted - was also able to grab a video [0].
So cool to see how far our detection of these objects is coming along, especially for something as small as this was.
