Was this cropped? I'd think camera rotation would normally make the center of the image the orbit point, not somewhere off to one side.

Regardless, its a really cool effect as said above.
I'd agree if it were a zooming lens, but for "rotating" the camera during a hold, the rotation point could be anywhere. The "hooks" at the left end of the light trails suggest that it was a complex movement.
I confess, I'm puzzled by the kind of "pulsing" effect.

Maybe the SR trying to keep up?

I think it must have been pretty dark, and the photographer hadn't been paying attention to the shutter speed. They had no idea the camera wanted such a slow speed, so they were changing the zoom and moving around while the camera was still trying to take the shot. I sometimes have that trouble when I pick up the camera in the morning and it's still in M mode and some settings from night tripod shooting.

If we assume the center of rotation of the camera is the wrist, it should be to the right, just as this image shows.

After my last post, I went out into the yard to replicate this. I was able to put the center of rotation pretty much anywhere. Here are two, one with rotation in the center, one with it off to the right, more like the OP. I chose 1/6 just like the OP, but had to dial down to f22 to keep exposure in check. Even then, these were about 1/2 stop overexposed.
