Winter Solstice elliptical halo

I was outside working on the day of the Winter Solstice and saw AC clouds coming in and I anticipated elliptical halo and got my camera gear ready. Not too long afterward I saw ice crystals precipitating out the AC and using a telephone pole as a sun block got a small elliptical halo. It came and went twice. This I believe is my 2nd elliptical halo for the 2019 year.
