Types of these phenomena are named for the 22-degree or 46-degree angles of minimum deviation that give rise to them. For 10 points each:

[10h] Name these refraction patterns around the Sun and Moon that are visible from Earth. Sun dogs and light pillars are types of these phenomena, which are formed by ice crystals in the atmosphere refracting light.

ANSWER: halos [accept 22-degree halos or 46-degree halos; prompt on rings or Bottlinger’s ring]
