This image was taken late at night and shows a luminous ring surrounding the moon. This is very rare and spectacular: it is called a Moon Halo and is an optical phenomenon.
A halo is formed under the refraction of light in a cloud containing ice crystals. A halo can appear in the sky at any time of the year, although it is most likely to be seen in winter. It most often appears over ice-covered areas and in the mountains.
Nikon D850 with Nikon 14-24mm lens. 15 seconds, f/4.5, ISO 400.
