Two views of a 22-degree circular #halo around the sun that I saw on a walk this afternoon.
Halos are a lot more common than I used to think. Then I started actually looking for them. Even on a warm day like today, there can still be ice crystals higher in the atmosphere of the right size and shape to cause a display like this (or even more complicated ones).
@kelsonv Not a lot of people actually look up, is what I suspect...
From over (OMG!) 40 years ago - during a class on history of science, in about 200 students, I was the only one who raised her hand when the prof asked if we had ever seen a "sun dog".
I'd seen my *first* one at least 15 years before that time - lots of family road trips meant I got to stare out the window a *lot*!
