The full Worm Moon makes its appearance on the night of Tuesday, March 7, 2023.
If you have just a bit of rain on either of these nights, you may even get to spot a rare phenomenon called a moonbow.
A moonbow is just like a solar rainbow, but is created by moonlight (rather than sunlight) when it is refracted through water droplets in the air.
Moonbows only happen when the full Moon is fairly low in the sky, so look for one in the hours after sunset when the sky is dark.
This March Moon will look especially large to us when it’s near the horizon because of the “Moon illusion,” when it looks bigger when near comparative objects than it does when it’s high in the sky without any references.
