Within minutes the visible part of the decreased. Then the moon seemed to melt. Not closed with a cloud, and just melted away... (According to D. A. Bolotnikov).
Review of A. D. Bolotnikova: Next day 20.12 in the same place. dark. Through the gaps between the clouds and stars visible. In one of them, the Moon appeared. But it was a narrow sickle of the young moon. And he to the East and higher than the day before. Yesterday's "moon" could not be the Moon!

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.
Light sources on clouds
Lasers, searchlights, car headlights and other light sources of sufficient power can form a column of light in a dusty or foggy atmosphere, various patterns on low clouds, fog or haze. Also, the rays can highlight parts of the cloud, objects or birds, giving them bizarre shapes.
Searchlights can shine with one beam, several. They can be stationary, move, and also form spinning carousels on the clouds, which can change shape and color.
It often seems that the light source is located at the point where the beam hits the cloud, and not vice versa.
Cloud (natural and man-made)
Clouds are the products of condensation of water vapor suspended in the atmosphere, visible in the sky from the surface of the earth. They consist of tiny drops of water and/or ice crystals (called cloud elements).
