The first supermoon of the year is coming to the sky TONIGHT...
A supermoon occurs when the moon is especially close to Earth while it's full.
This year, the March full moon will also be the first of three straight full-moon supermoons As we will also have Supermoon's in April and May.
The March full moon, is also known as the "worm moon,". That name, some say dates back to the Native Americans as this time of the year, the ground begins to soften for earthworms to reappear, inviting birds to feed.
