According to the Aesthetics Wiki: "Frutiger Aurora is a subgenre of Frutiger Aero that focuses on the aurora visual; an aurora is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Frutiger Aurora emerged in the Early-2000s towards the end of the Y2K era and maintained it's popularity into the Early-2010s."
