The Blue Moon of August 2023 rises in just one week, offering skywatchers an extra treat this month with another supermoon.
The Blue Moon will rise on the night of Aug. 30. Look to the east just after sunset to find it; it won’t be difficult to spot given it will be the brightest and largest moon of the year. This moon is notable for a few reasons: For one, not only is it a full moon, but it’s also a Blue Moon, which means it’s the third full moon in a season that has four full moons, according to NASA.
Plus, this Blue Moon is also a supermoon, meaning it coincides with perigee, the point in the moon’s orbit when it’s closest to Earth. For observers on the ground, that means it will appear slightly larger than normal, though only about 7% bigger. With the unaided eye, this size difference probably won’t be noticeable.
The Blue Moon of August 2023 will also be joined by a special guest in the sky: Saturn.
The ringed gas giant will be just a few days past opposition, the point at which it lies directly opposite the sun as seen from Earth, making it especially bright in the night sky.
As viewed from New York City, Saturn will be in the constellation Aquarius, above and to the right of the moon. From the Southern Hemisphere, however, Saturn will appear below the moon.
Blue Moons occur relatively frequently, astronomically speaking, happening once every two to three years. The last Blue Moon rose in August 2021, and the next is expected to rise in August 2024.
