Mother Nature is celebrating the first day of spring with supermoon! 

Tonight, March 20, a “full worm super moon” will rise, marking the first supermoon of the month and the last until 2020. 

According to the Old Farmer’s Almanac, “the last time the full moon and the spring equinox coincided this closely (four hours apart) was in March 2000, but the last time they occurred on the same date was on March 20, 1981.”

Supermoons are well known to appear bigger and brighter than the average full moon, with tonight's show set to begin just after sunset at 7 p.m.

But what exactly is a "full worm" super moon, well that interesting distinction comes courtesy of the Old Farmer’s Almanac and refers to the releasing of earthworms from the frozen ground as winter thaws and spring is welcomed.

It has also been referred to as the “sap moon” as March begins maple syrup season as well.
