I rediscovered this picture of a parhelion or ‘Sun Dog’ on some beautiful wispy, icy clouds. It looks like it was taken some time in spring based on the position of the sun. This optical phenomenon is caused by flat hexagonal ice crystals refracting sunlight by 22º. The effect can also cause a halo at this distance from the sun, and even the moon. Light dramatically reflects off the ghostly swirls above it and the contrast in the background blues makes a lovely composition.
