Two parallel rainbows, twinned bows, which in the images are no longer really faintly visible in the middle of the image, slightly to the right.
It was a thunderstorm day, and in this deafness I saw something I didn’t think was right at first - two parallel rainbows next to each other. I invited the other attendees to wonder, and then I only realized to pick up the camera even if the phenomenon still existed.
If anyone would get a better look at them. At the Atoptics.co.uk page then, I found better pictures of it, and realized I had seen something real though.
