The Purple Edge — Rare Violet Aurora Bands

Aurora night film, 13 seconds, 16:9, 24fps, low-light 4K. A sub-storm night in the far north: the aurora burns in an unusual palette, violet bands edging the green curtains, the lower border fringed with red, the whole display breathing like something alive against the black sky.
0-3s: The drone holds wide as the violet edge ignites along the green curtain, the fringe pulsing slowly like a heartbeat, colors shifting and bleeding at the borders. 3-7s: The drone tracks slowly along the violet-edged bands, the violet deepening and thinning in waves, the red fringe flickering at the bottom edge, the green core churning. 7-11s: The display surges once, violet flooding outward across the sky, the bands brightening to electric intensity, then the pulse eases. 11-13s: The aurora settles back into its rhythm, the drone holding on the rare palette until the end, the violet edge still burning.
Subject: the aurora in its rare violet-green-red configuration over a dark northern landscape. Camera: a slow lateral track along the bands, minimal movement, the sky doing the work. Lighting: the aurora itself, violet and green against black. Atmosphere: rare, vivid, electric, a once-a-season sky. In the last seconds a faint second arc kindles behind the first, violet on violet, and the drone holds as the two bands breathe out of sync, the rarest sky doubling itself before the night reclaims it.
Style: low-light 4K, natural night color, long-exposure feel, 24fps.
