The beautiful image, photographed by Dani Caxete, depicts a beautiful moon near Madrid, Spain, whose appearance was crystallized into having a quadruple halo due to falling ice crystals. Such a view, with a 22 degree halo, is very rare. The 22 degree arc is elongated by "column ice crystals" then also further refracted through more distant ice crystals to give the semblance of a 46 degree, rainbow-like halo. The lovely scene, as though it had been taken from a Christmas storybook, is set also by the Sierra de Guadarrama mountain range. The winter night sky scape includes many of the classic winter constellations with such stars as Sirius in Canis Major, Orion's Belt stars, and Betelgeuse within the arcs.
When the arcs and halos around the moon occur, they can be visible anywhere between a few minutes to a few hours.
