WxOpti2626_071  (November 1990)
Above the house silhouette are iridescent clouds with pastels of green and red. If the sky had a uniform coverage of thin clouds like these, a corona may have been visible which would be more circular and centered around the sun like a kind of halo.
    Location: CO, Fort Collins

WxOpti2626_072  (November 1990)
A street lamp is used to eclipse the sun and better reveal the iridescent cloud. This phenomenon is VERY common though not usually this impressive - you only need to take the time to look for it whenever the sky has very thin cirrus clouds.
    Location: CO, Fort Collins

WxOpti2626_076  (November 1990)
Unlike haloes which require clouds composed of ice crystals, iridescent clouds can be caused by clouds composed of either water or ice.
