This is my first run-in with a solar halo phenomenon that isn't a sun dog or 22° halo, save for the 9° halo that I photographed at Laguna Beach.
It's uncommon, frankly, but it's still a find.
A sun dog can be found rightwards to this sun as well.
I took a picture of this mesmerizing cloud display in the morning, which appears to be altocumulus(?) translucidus radiatus [the larger lines] with a layer of cirrocumulus undulatus occupying the majority of the space above the radiatus clouds.
I'm still skeptical on the radiatus clouds being a variety of altocumulus though, because of the composition of the lines of cloud on the near end of the picture, not looking like typical altocumulus. If you can, give me your personal observation on what the cloud types pictured are.
During my trip to Laguna Beach, CA, I obviously saw the 22° halo here, but what I didn't notice when taking the picture was what appears to be a 9° odd radius halo as well.
Odd radius haloes need their own flair...
