Additional imagery is at the 20150525 entry of my raw images.
Charles' camera was a raspberry pi camera module running at 90 fps with a rolling shutter. So you can see the exciting bit sort of roll by over two or three frames.
My camera was a cion running at 60 fps with a 180 degree shutter. So 1/120 second exposure and then nothing for 1/120 second. Thus the first and third images have the arc, but the middle one missed the arc and shows only the fireball.
