Sunny Sundog Icy Morning

Commonly known as a “Mock Sun” or “Sun Dog, this is a Parhelian or “Mock Sun” It occurs at 22 degrees angle from the sun. There are many manifestations of this. I’ve only seen one better Parhelian off the face of the Jackson Hole Ski area. At the Village in Jackson Hole mid winter back in the 90’s. This capture was a few miles back in the backcountry while I was driving parallel ridges for that mornings sunrise. This images sits on the border between Montana and Wyoming with both states ground and sky in the image. I never know what I’m going to run into when I go out.

Caused by Reflection and Diffraction is the slight bending of light as it passes around the edge of an object. In the atmosphere, diffracted light is actually bent around atmospheric particles – most commonly, the atmospheric particles are tiny water droplets found in clouds. Diffracted light can produce fringes of light, dark, or colored bands. Here Hexagonal plates of ice are falling actively from the sky. You can actually see some of them like white dots on the image. Ice Hexagonal plates Frozen in Space and Time as they fell (literally and figuratively).

It was a cold subzero morning for this sky show. This ice was hazing up the whole sky but I actually drove into this from an area with no falling ice. POP and there was an entire Parhelion right in front of my camera. Slide to a stop, enjoy the view while the camera comes out of sleep, compose, set the final settings, focus and click. The image is about 60 degrees wide overall. Love the Lone tree sun filter.

This big old sun dog happened one cool sub-zero morning. Ice crystals refracting light were falling out of the air in front of my camera everywhere. All the white speckles are ice crystals close to the camera. I was just driving along a high ridge as is my typical backcountry drive. It suddenly appeared as I was driving along. The ice fall moved over me.

Two ways these form:. 1: light passing through suspended atmospheric plate-shaped hexagonal ice crystals in high and cold cirrus or cirrostratus clouds. Alternately, refraction from drifting in freezing moist air at low levels as diamond dust as here. Those “mock suns’ are from the aforementioned “Diamond Dust”. The colors usually go from red closest to the sun outward with the standard rainbow sequence. This was VERY bright.

This half circle halo is 22 degrees from the sun. These 22 degree refractions are present with and without mock suns in my experience. This particular Sundog even has a sun pillar above AND below the sun itself. Pillars develop as a result of ice crystals slowly falling through the air, reflecting the sun’s rays off of their hexagonal flat surfaces.

I’ve only seen one better sundog off the face of the Jackson Hole Ski area at the Village mid winter back in the 90’s. This was a few miles back in the backcountry pretty much across the border with sky in both Montana and Wyoming. .
