Details:
I think the lunar halo is more spectacular than the solar one because it has stars, planets and constellations as a background.
Having a radius of 22°, whatever the height of the Moon, it can contain entire constellations within it.
In these pictures shows a lit lunar halo that contains within it the entire constellation of the twins with Castor and Pollux shining in the colored band of another phenomenon of colors: a Corona.
The two phenomena, halo and corona, are not formed by the same type of clouds which is why it is rare for these phenomena to occur simultaneously.
In particular, the crown in the photo can be defined as a lunar multi-crown as it has very extensive colored concentric circles and very bright colours.
The halo occurs when light from the Moon is refracted through ice particles suspended in Earth's atmosphere
These particles act like prisms, separating light into different colors and creating a colorful halo around the Moon.
The lunar halo appears as a ring of light around the Moon, usually white or silver in color, but can sometimes take on shades of other colors such as red, blue, or green.
The lunar phase is essential for its formation, in fact if the Moon is not bright enough you cannot witness this wonderful formation…
The crowns testify to the wave nature of Light. In fact, their formation is favored by the diffraction and interference of light at the edges of small water droplets or crystals present on veils of clouds such as cirrocumulus, stratocumulus, or even by pollen, dust or aerosols.
Smaller droplets produce larger coronas, larger droplets produce slightly smaller or dimmer coronas.
