Lunar Halo

Last Saturday we were a bit confused with a first-of-our-lifetime experience of seeing a large ring around the moon.  Turned out to be a Lunar Halo, the light being refracted and reflected by high-altitude ice crystals.  It did add some extra spookiness to the Halloween evening.

According to rhyming folklore, 

"A ring around the sun or moon 

  means rain or snow is coming soon."
