A very unusual glowing circle was observed around the Moon in the sky over Baku. Experts say that this optical phenomenon (a luminous ring around the object - a light source) is called Halo (also known as a nimbus or Gloriole).
Halos are visual phenomena that appear near or around the Sun or Moon, and sometimes near other strong light sources such as street lights. There are many types of optical halos, but they are mostly caused by ice crystals in certain types of clouds. The shape of the crystals changes the type of halo seen. Light is reflected by the ice and may split into colors, similar to the rainbow.
