Today I flew to Toronto for a speaking gig. I had this awesomely spacious window seat in the exit row. I was looking out the window as we descended into a bank of what the pilot called ‘medium-low cloud’, and spotted this odd, multi-hued circle in the distance. I wondered if it was just a deformity in the window, but I’m pretty sure it wasn’t:
It looks like a rainbow’s cousin (here’s another, very similar view). Does anybody know what it’s called?
