Diamond Dust Sundogs in Utah: A Phenomenal Display of Atmospheric Optics

Utah, known for its stunning landscapes and natural wonders, is also home to a mesmerizing atmospheric optics phenomenon called "Diamond Dust Sundogs." These enchanting displays of light occur when diamond dust plate crystals drift in the subzero air, creating a spectacle that captivates both locals and visitors alike.

Sundogs, also known as parhelia, are optical phenomena that appear as bright spots of light on either side of the sun. They are not physical objects occupying a specific region of space; rather, they are the result of particular angles from the sun along which millions of crystals glint their light most brightly. Imagine witnessing a rainbow, but instead of vibrant colors, you are greeted with ethereal bursts of light.

The diamond dust crystals responsible for these sundogs are tiny, hexagonal ice crystals that resemble flat plates. They form in extremely cold temperatures when moisture in the air freezes into ice crystals before it has a chance to form into snowflakes. These crystals are so small that they can remain suspended in the air, creating a magical effect as they catch the sunlight and scatter it in different directions.

To witness the beauty of diamond dust sundogs, one must be fortunate enough to experience the perfect combination of subzero temperatures and atmospheric conditions. Utah's cold winter months provide the ideal environment for these displays to occur, as the state often experiences temperatures that plunge well below freezing.

When conditions are just right, the diamond dust plate crystals fill the air, creating a breathtaking scene. The sundogs appear to be in front of distant hills, giving the illusion that they are tangible objects. In reality, they are optical illusions caused by the interaction between light and ice crystals suspended in the atmosphere.

As the sun rises or sets, its rays pass through these diamond dust crystals, resulting in the refraction and reflection of light. This phenomenon causes the sundogs to emit a radiant glow, with glints of individual crystals appearing as white specks. The vertical line through the sun, known as an upper and lower sun pillar, adds to the spectacle, while the parhelic circle extends brightly beyond each sundog.

The beauty of diamond dust sundogs lies not only in their visual appeal but also in their rarity. Witnessing this atmospheric phenomenon is a testament to the intricate and awe-inspiring workings of nature. It serves as a reminder that even in the coldest and harshest of conditions, there is beauty to be found if one takes the time to look.

Next time you find yourself in Utah during the winter months, keep an eye out for these stunning displays of diamond dust sundogs. Remember to dress warmly and be patient, as these magical moments are unpredictable and fleeting. Embrace the marvels of atmospheric optics and let yourself be transported into a world where light dances with ice crystals, creating a sight that is nothing short of extraordinary.

Sunrise diamond dust sundogs. Imaged by Don Brown of Park City ( Utah Skies ) on February 7, 2003. The sundogs appear to be in front of the distant hills because they were created by diamond dust plate crystals drifting nearby in the subzero air. Glints of individual crystals can be seen as white specks. Sundogs do not occupy a specific region of space, you could no more catch one than you could a rainbow. They are more the mark of particular angles from the sun along which millions of crystals glint their light most brightly. The vertical line through the sun is an upper and lower sun pillar. Horizontally through the sun and extending brightly beyond each sundog is part of the parhelic circle. ©2003 Donald Brown, reproduced with permission.
