Superstition says a ring around the moon foretells an impending storm and that the number of stars seen inside the ring predicts the number of days before it starts.
Actually, according to meteorologists, a ring around the moon can indeed indicate an impending storm because it may mean that there is an excess of moisture in the air.
On September 29, 2012 a ring formed around the moon which got people buzzing. It was a nearly full moon, and the clouds in the sky were very high and thin; in the fall and winter in particular this can cause a halo, or ring to form around the moon.
Other moon superstitions include the belief that when the moon points upwards, the weather will be good and when it points downwards, it will rain.
When a large star or planet is near the moon expect violent weather. Fog and a small moon together bring easterly winds.
