Some people use the Moon to predict the weather on Earth.
Fun Time Determine if a lunar corona or halo can indicate whether fair or stormy weather is coming. Observe the Moon as often as possible, checking for the presence of a corona or a halo. When you see either one, note the weather conditions that follow. On some evenings, a corona or a halo is seen around the Moon. Lunar coronas appear to touch the circumference of the Moon, and lunar halos encircle, but do not touch, the Moon.
