A ring a round the sun or the moon is the commonest of the halo phenomena. It is the 22° halo formed by refraction of sunlight or moonlight through ice crystals with faces at 60° to each other, the commonest shape for ice crystals. The ice crystals are in cirrostratus cloud which is a thin veil of cloud which can be difficult to see. A halo is a positive identification of cirrostratus.
In high latitudes, cirrostratus is often the forerunner of a warm front which mean rain is probably on the way. In lower latitudes it just indicates the presence of moisture in the upper troposphere and is not a sign of rain on the way.

why do you have a problem with the letter "H"?
anyway, there are no rings around the moon. when you look up at the night sky, you are actually seeing the earth's atmosphere (which is mostly moisture) in front of the moon

Ice crystals that have formed in the upper atmosphere.

that is actually ice crystals high in the atmosphere and moon light reflecting on them

Count the number of stars you can see within the ring. The number of stars you see will be the number of days until it percipitates (Old wives tale).
