Here are the ice halo pictures I took in Minneapolis last Friday. I should have tried for a shot including the sun, but I was in a hurry.
The shot below was taken through a tinted third floor window a little while after the one above.
Pretty day. I started to write something about wishing I could have spent it outside instead of in a classroom, but then I remembered how cold it was. I think it was around 6 degrees at the time. Later on it warmed up a bit, to the mid-teens or so, but there was enough wind to make flags unfurl completely. Going to and from the car was more than enough outside time for me.
