last night after dinner I noticed a ring around the moon, and It was pretty amazing. I asked folks around if they can see it or is it only me ;). I searched on internet and found this.
"This ring around the Moon is caused by the reflection of Moonlight (which of course is reflected sunlight) from ice crystals in the upper atmosphere. The shape of the ice crystals results in a focusing of the light into a ring. Since the ice crystals typically have the same shape, namely a hexagonal shape, the Moon ring is always the same size. "
