Green Aurora Corona Over Sapporo Winter Ridge

Vivid emerald light erupts in a tight, circular corona directly overhead against a star-strewn black sky. The aurora radiates sharp, vertical rays that fan outward from a brilliant center, illuminating the frost-covered ridgeline below. A dark silhouette of a person stands at the edge of the slope, framed by the glowing green column. The ground is coated in a thick layer of white snow, untouched and crisp under the starlight. The air appears exceptionally clear, allowing the stars to shine with piercing intensity above the luminous display. The contrast between the deep shadows of the ridge and the electric green glow creates clear immense vertical scale. At the very bottom edge, the texture of frozen grass blades pokes through the snow, sharp and distinct against the dark earth.
