A mock sun, also known as a parhelion or sun dog, is a bright, rainbow-colored spot that appears on either side of the sun. 🌈☀️ Think of them as the sun's little sidekicks! They are created by sunlight refracting through ice crystals in the atmosphere. Mock suns are usually seen on a parhelic circle (a horizontal ring of light at the sun's altitude). They're often reddish on the side closest to the sun and bluish on the side farther away. They are best observed when the sun is low on the horizon, making them look especially striking.
