(CNN) A Snow Moon will appear from Friday evening to Monday morning, but don't worry: it won't affect the weather.

According to the Farmers' Almanac, northeastern Native American tribes referred to the second full moon of winter as the Snow Moon because of February's heavy snow.

This month's moon is also being called a supermoon by some experts, which means it will be one of the biggest moons of 2020 and will look especially large when rising and setting.

However, experts disagree on what constitutes a supermoon, according to EarthSk y. While Fred Espenak, known as "Mr. Eclipse," lists this weekend's event as a supermoon, others argue it's not, EarthSky says. Astrologer Richard Nolle counts this year's first supermoon as occurring on March 9.

A supermoon is a full moon that occurs when the moon is at the closest point to earth in its orbit. This moon is important for other reasons as well, according to NASA. The full moon signals the start of Jewish celebrations of Tu BiShvat, known as "New Year of the Trees."
