Is That A St. Patrick’s Day Moonbow?

If you have some rain today for St. Patrick’s Day, you may get to see a rare weather phenomenon.

A pot of gold at the end of a rainbow is often a part of St. Patrick’s Day decorations, but have you seen a moonbow? A moonbow is like a solar rainbow but is created by moonlight refracted through water droplets in the air.

Moonbows only happen when the Full Moon is fairly low in the sky and rain is opposite the Moon, so it might be visible tonight or tomorrow in the hours after sunset when the sky is dark.

If there is a pot of gold at the end of a rainbow, I wonder what you would find at the end of a moonbow.
