Sun dogs are usually seen around here when it is bitterly cold, so it was a bit unusual to see this one on a day when the temperature reached 40 (4.4 C). (What a change from yesterday when the windchill high was around -15F or - 26C!)

I have to be out of town for a couple of days so I'll be working on catchup when I get back Monday.
