I sent this photo to WRAL and Mike Moss of the weather bureau was kind enough to reply with the following explanation of what I photographed at 8:06 AM this morning at the Jordan Lake dam using my iPhone 5S. The photo is not edited in any way.
“Hi Ellen, You captured a nice example of the 22-degree halo, formed by light passing through a layer of millions of tiny hexagonal ice crystals that happen to be both well-formed and more or less randomly oriented. That happens on occasion with sheets of high cirrus clouds like those passing over the area this morning.”
[the small green dot at the top of the halo is from my iPhone]
