A Snow Moon appeared at its fullest at 2:33 a.m. ET on Sunday, February 9.

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 EarthSky. 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.
