How is it that I’ve never come here before??

In the photo below, I think the apparent concentric rings occur because pine needles that are tangent to the circle formed by the sun and their midpoint, will reflect light to the camera from all along their length, while others will not.

It’s the same reason we sometimes see light streaks on windshields at night (in this case, because of striations caused by windshield wipers, and headlights from a car coming in the opposite direction).

More elegantly, it’s also why we sometimes see sun-pillars over the setting sun.  In that case, it’s because snowflakes in the atmosphere often orient themselves horizontally.
