Bisected Halo

A circular halo around the sun, which is behind a tree. A contrail crosses the halo, leaving its shadow on the thin cloud layer below.

A clear 22-degree halo around the sun, bright enough that I didn’t have to adjust the image afterward. This is straight from my phone.

Even cooler: you can actually see the contrail’s shadow on the layer of cloud that’s producing the halo! The sun is behind the tree, and while the contrail pops out so it looks closer than the almost uniform layer, it’s clear from the shadow that the contrail is higher.
