I took this picture a few minutes ago (35 minutes ago, currently 1828 here)
As you can see there's a VERY bright spot on the right that shows a spectrum on the one side.
I am pretty confident it's the reflection from a large body of water there are quite a few reservoirs around.
However I do have some questions:
- Why do the colours band only on one side
- Why does it move (when the sun sets approximately 35 degrees to the right of where it is now this shape can appear to the right of the sun, not left!)
- Why is it only sometimes there? (Perhaps it is blocked by hills sometimes?)
How can I model where it is?
I took a picture 15 minutes later and both the sun and the bright spot had gone lower in the image. I could try and model this as a point light hitting something on a plane and approximate the height of clouds and such but sun isn't a point and the earth isn't a plane.
I have spotted this thing elsewhere and have been pondering on modeling such things for a while. I've gotten no where. It's not an urgent question but it is a curiosity.
