Солнечное гало над Стокгольмом

A Sun Halo Beyond Stockholm: "A Sun Halo Beyond Stockholm
What's happened to the Sun?

Sometimes it looks like the Sun is being viewed through a large
lens.

In the above case, however, there are actually millions of lenses:
ice crystals.

As water freezes in the upper
atmosphere, small, flat, six-sided, ice crystals might be formed."
