A pair of rainbow‑hued sundogs flank the sun over a rural road near Elk Point, S.D., on Dec. 29, 2025. The colorful optical display, caused by sunlight refracting through ice crystals in the upper atmosphere, is known as a parhelion. Sundogs often appear on cold, clear mornings when the sun is low on the horizon. Photo by Shannon Jost • timesleader1@gmail.com
