Officially, the full moon peaks at 1:48 p.m. EDT on Monday afternoon when the sun is out.
The next full moon will also be a supermoon, and will occur in a month, on April 7.
This time about, it's called the Worm Moon because - historically - it's the time of the year when the rains start to soften the ground underfoot after a long cold winter and the worms start to head for the surface once again.
Supermoons happen when the moon's elliptical orbit brings it to the closest point to Earth while the moon is full.
Moons are named after features in specific seasons they are typically associated with.
It is typically the last full moon before the vernal equinox, or the first day of spring, which can take place on March 19, 20, or 21. The moon will appear full from Sunday through Tuesday night, visible to skywatchers if the weather remains clear.
Despite being closer than it usually would be, the moon is still a decent whack away from us.
The Super Worm Moon is the second in a series of four straight months that include a "supermoon". You'll be able to spot it above the horizon from 5.35pm on Monday.
The nicknames bestowed upon the full moons were originally designated by Native American tribes in the Northeast in order to help keep track of the seasons.
It's also called the Lenten moon, crow moon, crust moon, chaste moon, sugar moon or sap moon, depending on where you live. The Super Worm Moon will be 222,081 miles/357,404 km from Earth, about 7% closer than the average of 238,855 miles/384,400 km. The most distant full moon of the year will come on Halloween.
