Initial data
UFO sightings in 1547 AD - Glarus, Switzerland
A large white cross, two golden lions and an army of black knights fought each other in the sky. At a certain point during the battle, one of the golden lions lost his head. This is how the incident is described in the manuscript of the Augsburg Book of Miracles ("Augsburger Wunderzeichenbuch").
Hypotheses
Halo
Halo usually appears around the Sun or moon, sometimes around other powerful light sources such as street lights. There are many types of halos, but they are mostly caused by ice crystals in Cirrus clouds at a height of 5-10 km in the upper troposphere. The form of the observed halo depends on the shape and arrangement of crystals. Reflected and refracted by the ice crystals, the light often turns into a spectrum, which makes halo look like a rainbow, but a halo in low light has a low chroma, which is associated with the peculiarities of twilight vision.
Mirage
Optical phenomenon in which the air in the result of the refraction of light rays in addition to items in their true position, see their virtual images in the direct, inverted or severely distorted.
Distinguish mirages:
- lower
- top
- side
Inferior Mirage occurs when a large vertical temperature gradient (drop it with the height) over a superheated flat surface, often desert or paved road. Usually this "puddle" on asphalte or sand.
