The final supermoon of 2019 will be during the Worm Moon and four hours after the vernal equinox.
While that phrase may sound like something out of a children's book, the name actually has a legendary meaning. However, for those who couldn't get enough of February's "super snow moon" or January's "super blood wolf moon" eclipse, the "super worm moon" will be the last opportunity for a while to see a supermoon.
Spring begins at 3:58 p.m. Wednesday.
"When a full moon appears at perigee it is slightly brighter and larger than a regular full moon-and that's where we get a "supermoon". Full moons that occur in March are often called "worm moons" because spring brings warmer temperatures - and, therefore, more worms, CNET reports.

That is not to say there will not be other full moons this year.
March's full moon is also called the sap moon because the sap of sugar maples begins to flow around this time of the year. It's also the first supermoon in almost 20 years to fall near the spring equinox. In fact, it can appear as much as 30 percent brighter than normal. Perigee happens because the moon's orbit is not a flawless circle, so there are times when it is relatively close to us on Earth and other times when it is comparatively far away.
The full moon is also known as the worm moon in some parts of the world.
Asteroids: In case you wanted more, the event will happen as an asteroid passes close to Earth, according to the Minor Planet Center. Unfortunately, local sky observers seem likely to face increasing clouds by late Wednesday.
