A rare lunar event is set to grace the skies this weekend, offering stargazers a unique opportunity to witness a phenomenon that will not be seen again until 2028. Known as a Blue Micro Moon, this event combines a Blue Moon with a micromoon, creating a spectacle that is both scientifically intriguing and visually captivating.
What Is a Blue Micro Moon?
A Blue Micro Moon occurs when a full moon coincides with the moon's farthest point from Earth in its orbit, known as the apogee. Despite the name, the moon does not actually appear blue. The term "Blue Moon" refers to the second full moon within a single calendar month, an event that happens only every two to three years. The micromoon aspect means the moon appears slightly smaller and dimmer than usual, though the difference is subtle.
When and How to See It
According to astronomy expert Alan Jones from 365 Astronomy, the Blue Moon reaches peak illumination on Sunday, May 31, 2026. However, the best time for viewing will be on Saturday evening, when the moon rises shortly after sunset and remains visible throughout the night. Jones advises choosing a spot with clear views of the eastern and southern horizons, away from tall buildings and trees, for the best experience.
Why the Moon Can Appear Orange or Red
As the moon rises or sets near the horizon, it can take on orange, amber, or reddish tones. This occurs because Earth's atmosphere scatters shorter blue wavelengths of light, allowing longer wavelengths like red and orange to dominate. Additionally, the well-known "moon illusion" can make the moon appear larger when it is low in the sky, even though its actual size does not change.
Is the Blue Moon Worth Observing?
Full moons are excellent targets for casual observers, families, and beginner astronomers. A Blue Moon carries a sense of rarity, reflected in the phrase "once in a blue moon." While not exceptionally rare astronomically, these events capture people's imagination and encourage more people to look up at the night sky.
Tips for Viewing and Photographing the Moon
Binoculars enhance the view, revealing darker maria and brighter crater regions on the lunar surface. Smartphones can capture impressive images when mounted on a tripod and used with manual exposure settings. For dramatic moonrise photos, include buildings, trees, or landscape features in the foreground to show the moon's scale against the horizon. For closer lunar photography, a telescope with an aperture of around 80mm or more provides crisp detail. Smart telescopes such as the Dwarf 3, Seestar S30 or S50, eVscope 2, and Vespera II are excellent beginner-friendly options for capturing detailed lunar images.
