Wispy Sundog Fragment

Wispy sundog fragment (colors enhanced). The colors were really easy to see through my polarized sunglasses, but just faded into the glare without them. My phone barely caught it, but the info was there once I stretched the saturation.

Spectrum at the top of the Sky

The colored wisp of cloud is too high in the sky to be a rainbow or a circumhorizon arc, and the spectrum is too ordered to be an iridescent cloud. I looked up ice halos that might produce this effect near vertical just before sunset. It turns out a circumzenithal arc is a perfect match: a rainbow arc near the zenith, brightest when the sun is very low. I’d never seen one before – it’s always cool to spot a new kind of sun halo.

Spotted November 12 at the Irvine Spectrum shopping center. It was around 90°F during the day at ground level, but of course it can be a lot colder in the upper atmosphere.

Saturation increased to show the colors more clearly.

Bright Lines at Sunset

Sunset Sundog
The bright line above the sun is just a contrail, high enough to catch the light without being tinted orange. The one off to the right is a sundog, ice crystals reflecting the sunlight. When I saw it I thought it was too far away to be an ordinary sundog, and might be part of a less common halo, but once I looked at how far away it appeared on camera (it’s all about the angle) I realized it was in the right place.
