The final supermoon of the year is coming this week and it’s happening with the official start of spring. Spring begins this Wednesday, March 20 at 4:58 p.m. CST.

The supermoon — this one is called the Super Worm Moon– will happen at 8:43 p.m. CST — several hours after the official start of spring.

Space.com reports that for people on the U.S. East Coast, the moon will rise about 20 minutes before sunset, by 7 p.m. and the moon will set the next morning at around 7:30 a.m.

The supermoon comes a day after the moon reaches perigree, the closest point to Earth, making the full moon a supermoon, which makes it appear slightly larger than the full moon usually does.

The ‘Worm Moon’ reportedly got its name due to the ground beginning to thaw and earthworms reappearing, according to the Old Farmers Almanac.

The Super Snow Moon lit up the sky last month. AccuWeather reports the next supermoon isn’t set to rise until Feb. 9, 2020.

When is the #SuperWormMoon 100% full?

A full moon is declared when the lunar disk is on the opposite side to Earth as the Sun, and 100% illuminated by the Sun. That occurs at the same global time, which this month is at precisely 01:42 a.m. UTC on March 21, 2019. That translates to the following time zones in North America and Europe:

01:42 a.m. GMT, March 21 (London)
