August continues to be an exciting month for sky-gazers. Closely following the peak of the Perseid meteor shower last week, the first of the year’s four consecutive supermoons is set to rise on August 19. The rare cosmic combination of a supermoon and blue moon peaks at 2:26 p.m. ET Monday.

The last time this lunar event occurred was August 2023, and the next super blue moons are projected for January and March of 2037. Approximately one-quarter of all full moons are supermoons, while a mere 3% of full moons are blue moons.

So-called supermoons appear as the biggest and brightest lunar events of the year. The moon’s orbit around Earth is not a perfect circle but an elliptical path. Scientists refer to the moon’s nearest point to Earth — an average distance of about 226,000 miles (363,300 kilometers) — along its 27-day journey as the satellite’s perigee, according to NASA.

There are varied definitions for supermoons, said Noah Petro, lab chief of NASA’s Planetary Geology, Geophysics and Geochemistry lab. However, a full moon within 90% of perigee is often described as a supermoon, he said.

When the moon is closest to Earth in its orbit, it can appear up to 14% larger and 30% brighter than when it’s at its farthest point from the planet, known as apogee, about 251,000 miles (405,500 kilometers) from Earth.

Why is it called the Full Sturgeon Moon?

It’s a name derived from a Native American tribe that used to track the seasons using the Moon. At this time of year the sturgeon fish, North America's largest lake fish, used to be caught in the Great Lakes, according to the Old Farmer's Almanac (it’s now critically endangered). The Full Green Corn Moon, Full Barley Moon, Wheat Cut Moon, Blueberry Moon, and Blackberry Moon are other names that have been given to August’s full moon by various tribes, again to indicate the harvest time for those crops. There are two chances to see the full moon at its most illuminated this month. Here are times for 10 cities around the world.

The Anishnaabe (Chippewa and Ojibwe) call it miini-giizis, the berry moon, while the Assiniboine of the northern plains named it capasapsaba, black cherries moon. The Lakota call it wasutoa wi, moon of the ripening, while the Sioux dubbed it cherries turn black.

Likewise the Tlingit have dubbed their August full moon sha-ha-yi, or berries ripe on mountain. Also in the fruit realm are the Wishram of the Columbia River in Washington and Oregon, who called it blackberry patches moon, and the Shawnee, with po'kamawi kiishthwa, or plum moon.
