Circumhorizontal Arc Over Uruguay Storm Clouds

Brilliant neon orange light stretches horizontally across a deep blue sky, forming a perfect fire-like band above a dark horizon. Below, massive thunderheads stack in layers of charcoal and slate, their flat bases defining the edge of the landscape. The sun has just dipped below the horizon, leaving a warm glow that illuminates the upper edges of the clouds while the lower atmosphere remains in shadow. The arc glows with intense saturation, contrasting sharply against the cooling blues of the clearing storm. Tiny wisps of cirrus clouds catch the fading light near the horizon line. The bottom right corner shows the rough texture of a distant tree line silhouetted against the bright band.
