'Rainbow spokes' on double rainbow nearing Swaffham Prior

Odd ripple effect on a double rainbow (admittedly not an organism, but a natural phenomenon, as far as I can tell). I hadn't ever noticed this before - any ideas? The 'ripples' are rather faint, but are at right-angles to the rainbow arch, inside the arch. Photo was taken from inside a moving car - maybe they were an artefact of that, but we could all see them.
