University Observatory Stairwell Red Night Bulbs

Golden hour light floods a symmetrical outdoor stairwell near a weather balloon launch site in Dali. The concrete steps rise evenly on both sides, framing a central path illuminated by small red night bulbs that cast deep crimson pools against the warm amber glow of the setting sun. Dry season dust settles on the rough stone surfaces, catching the low-angle rays. Metal handrails run parallel along the ascent, reflecting the dual light sources. The clear sky above shows a gradient from bright orange to soft violet. At the top landing, a small vent pipe stands against the fading horizon line.
