This doesn't answer your question, but I was in England a few years ago and at the White Cliffs of Dover saw 22 rainbows in the sky at once.

Truly spectacular.

What was the light sources? A rainbow is always antipodean to the light source, and at best you might see three on a single rain front using the sun as the source (with two and three each being less intense). I guess it is possible to have a secondary rain front behind the first, but 22 seems like there must be multiple artificial sources.
