This particular supermoon will be the biggest and brightest of the year, because it is full closest to the point of perigee.

Wait, what does that mean?

Thanks to the Lowell Observatory, we have a lovely educational video that will tell you all about tonight’s big event!

From CNN:

The first full moon of spring, its name comes from native North American wildflowers that bloom in early springtime: Phlox subulata, known as “moss pink,” according to the Old Farmer’s Almanac. April’s full moon has also been known as the “sprouting grass moon” or “egg moon,” heralding other first signs of spring.

The moon itself won’t look pink, but it may appear more golden as it rises above the horizon. That’s due to an effect caused by our atmosphere, similar to how the sun can appear more red as it rises and sets, according to NASA.

Normally, there are 12 full moons in a year because one occurs each month. But in 2020, October will have two full moons, one on October 1 and then again on October 31.

Two full moons in the same month is known as a “blue moon.” And the fact that the second one falls on Halloween truly makes this event “once in a blue moon.”
