You can see what looks like Jetwash coming out the wrong way just to the right of the engine and this strange distortion was in every photo I took of it. It was only 2 days later that I found the cause having noticed on my last rear view shot that it has a highly polished flap causing the sun to be reflected backwards onto the fuselage.
