“The first full moon of the month, known as the flower moon, reaches peak fullness at 1:23 p.m. ET on May 1.” This statement comes from Catherine Pilachowski, an astronomer. May 2026 will feature a rare occurrence of two full moons, including a Blue Moon at the end of the month.
The first full moon of May is called the Flower Moon. It gets its name from the blooming of flowers in spring across North America. This moon will be visible at 99% illumination on the nights of May 1 and May 2.
Key facts about the Flower Moon:
- The Flower Moon rises in the southeastern sky after sunset on May 1.
- A lunar halo may be visible around the Flower Moon due to ice crystals in Earth’s upper atmosphere.
- It is associated with various nicknames, including Budding Moon, Frog Moon, and Planting Moon.
The second full moon of May 2026 is known as the Blue Moon. It will occur on May 31 at 4:45 a.m. ET. This Blue Moon will be a micromoon, appearing 6% to 7% smaller than average.
The last blue moon occurred in August 2024 and was notable for being a blue supermoon. The term “blue moon” refers to a second full moon in any month. Pilachowski noted this distinction clearly.
The Flower Moon and Blue Moon provide excellent opportunities for astrophotography enthusiasts. Skywatchers can expect stunning views during these celestial events.
