Fire Blob in the Sky

Last night, I was awake in the night, due to some loud illegal fireworks.  I couldn't get back to sleep immediately.  Later on, about 3:30 a.m. I looked out my window, because I thought I heard a car out front and saw a fire ball in the sky, not very high up, looked about basketball or volleyball size. It drifted along, with the wind, like a balloon would.  I grabbed for my camera and fumbled over it, trying to get it on and then to find the thing, that was drifting SW over the end of the cul de sac by then.  I didn't think I got anything on camera, but found that I did in just a few split seconds, on the video.  So I took screen shots of those split seconds.  There was only one fire blob, but I took the photo through the window.  Looks like a Japanese lantern turned loose on the night, but in these extreme fire conditions?  Is this some arsonists tactic?

This shot shows the photo distortion caused by low light conditions, because that light on the left is actually a neighbors garage light.  Then you can see the blob, on the upper right.  This is just about the time it vanished, and was very low.

Same thing again, only this shows two neighbor's lights, one on the far left, one in the middle, then the fire blob up there on the right.

Well, the night sky fire blob is long gone, but it made my night a bit interesting, at least.
