Orb with halo photographed over Portland

On January 29, 2016, an inhabitant of Portland (Oregon) was in their home to take a photo of the sun. When he has reviewed his picture, he has discovered with surprise an impressive orb with halo.

Witness report:

I was out on the back porch taking pictures of the roof and my dogs. I thought of taking a picture of the sun as it sets as I do several times a year. So that was what I did. I did not even review my pictures that I had taken until the next afternoon. At that time is when I found the object.

I am curious as to if this or similar has been seen elsewhere.
