This breathtaking phenomenon is known as a "fire rainbow," or scientifically, a circumhorizontal arc. It occurs when sunlight refracts through millions of hexagonal ice crystals suspended within high-altitude cirrus clouds. For this rare optical display to manifest, the sun must be positioned extremely high in the sky—at least 58 degrees above the horizon—and the ice crystals must align perfectly parallel to the ground.
Because the vivid pastel hues spread horizontally across the clouds, many people mistake the visual for a digital edit. In reality, it is a magnificent display of atmospheric physics. These rare moments are fleeting, often lasting only a few minutes before the sun shifts and the colors vanish.
While the absolute authenticity of this specific image remains unverified, identical fire rainbows are documented globally, proving that nature creates palettes that defy imitation.
