Hi everybody, long time no visit here and I see some new people and lots of beautiful things. I recently shot what I thought was a 22 degree halo, but then it struck me that it’s oval, so I did some looking up. Atoptics says it’s a circumscribed halo. Interesting how its shape varies with the height of the sun.
