Under specific conditions, sunlight or moonlight is refracted, reflected, and dispersed as it passes through hexagonal ice crystals within thin cirrostratus clouds. This process can produce luminous rings, arcs, pillars, or intensified beams of light radiating from a bright source. The apparent symmetry and vivid colors result from precise crystal orientation, low solar or lunar elevation, and exceptionally clear atmospheric layers. These effects are governed by well-understood principles of geo
