Spring Equinox Moon 2019: What is a Worm Moon? Can you see the Super Worm Moon tonight?

What is a Worm Moon?

The March Full Moon earned its name after Native American tribes observed how worms reappeared at the start of Spring as the ground stared to thaw.

At 7.45pm GMT (3.45pm ET) on today, Wednesday, March 20, the Moon will be a mere 223,309 miles (359,380 kms) distant from Earth, making this a particularly close perigee.

Then, at 1.45 am GMT early on Thursday morning (9.43pm ET on March 20), the Moon will finally reach its full phase.

As a result of these combined events, the full lunar disk will appear approximately 14 percent larger and 12 percent brighter than usual — a phenomena known as a Supermoon.
