There are times when I’m flying and the clouds are just right to focus the suns light into a bright spot that follows the plane for several minutes. It is clearly some sort of reflection or refraction of the sun. What I like here is that you can see the sun, the sun’s reflection off the wing, the weird cloud effect *and* some lens flare so you can tell that the weird sun thing isn’t just in the lens. I could see it with the unaided eye … and now you can too.
