Subparhelic circle


On June/3/2006 at 20:20 CEST Susanne Danßmann observed a subparhelic circle on a flight from Berlin to Zurich. The elongated spot of light in the center of the image is likely a subanthelion. The shadow on the winglet suggests the photo was taken in direction of the antisolar point. There is no shadow of the airplane in the center of the subanthelion, because the airplane was high above the clouds.

Very nice image!

I think this is a left 120-degrees subparhelion instead. The sun was low, and the shadow of the trailing edge on the winglet appears to go straight down. Thus, the direction of the sun was approximately parallel to the trailing edge of the wing, which makes an angle with the direction of the bright spot on the subparhelic circle. If it were a subanthelion, the winglet would appear to be almost completely sunlit.
