???? Title
Fire Rainbow – Circumhorizontal Arc in Sunlit Cirrus Skies

???? Description
A vivid circumhorizontal arc, often called a “fire rainbow,” appears among wispy cirrus clouds in a sunlit sky. This rare optical phenomenon occurs when sunlight refracts through ice crystals at high altitudes, producing a brilliant spectrum of colors. The arc’s radiant hues contrast beautifully with the soft cloud textures, capturing a fleeting moment of atmospheric wonder. Ideal for editorial, scientific, and conceptual use across nature, weather, and fine art platforms.
