Rain or shine, Mother Nature is going to light up the sky this weekend with the first supermoon of 2020.

According to NASA, "The moon will be completely full on Sunday, Feb. 9 at 2:33 a.m. ET, but will appear full all weekend, from about Friday evening to Monday morning."

Because it's in February, this particular supermoon is also called the snow moon. Other names for it include storm moon, hunger moon, Chinese Lantern Festival moon, and the full moon of Tu B'Shevat.

The term “supermoon” was coined in 1979 and is often used today to describe what astronomers would call a perigean (pear-ih-jee-un) full moon: a full moon occurring near or at the time when the moon is at its closest point in its orbit around Earth. Because of this setup, these moons appear slightly brighter and larger than a regular full moon, making them popular with photographers and night-gazers alike.

Looking ahead, the next full moon will also be a supermoon, and will occur in a month, on March 9.

Of course, viewing conditions this weekend will depend on the weather.

Here's to hoping the skies over the Emerald City finally clear up and give us a view.
