IOWA (KCCI) — People in Iowa woke up Monday morning to a stunning “sun dog” in the sky.
Many KCCI viewers sent in their photos of the phenomenon, which is caused by the refraction of sunlight by ice crystals in the atmosphere.
Sun dogs typically occur during cold, clear mornings or evenings when the sun is low on the horizon, commonly in winter or early spring.
The spectacle was visible all across the state, from Boone to Des Moines.
