snowfalcon2,
Actually I have seen this effect incountable times when flying. I think there is even a name to it: "pilotīs glory".
But I used to think that this effect is caused by backscattering light, what donīt seems quite be the case here. In fact the region is less, not more, bright than the rest of the image, or parts of the image at least.
