Double Rainbow Plus

The summer solstice is a perfect time to catch a late evening rainbow at my location as it positions to arc over Mount Lorne and the lake next to my home. I was warming leftovers for an already late supper when I saw this one forming in a slowly approaching thunderstorm ... better a very late meal, twice reheated, than to miss a good rainbow! The display persisted for a remarkably long time and I made many exposures as it morphed. The fragmented, non-concentric third bow in this image is a bit of a puzzle. It appeared only in my last several shots, taken after the rain had finally reached the lake. Could it have been produced by the sun reflecting off the water?
