The Flower Moon is named for the blooming flowers of May, marking the peak of spring. It is the first full moon of the month and is associated with various nicknames, including Planting Moon and Milk Moon.

In total, there will be two full moons in May 2026. The second will be a rare Blue Moon, occurring on May 31. This event is particularly notable as Blue Moons happen approximately once every two to three years.

As the Flower Moon rises low in the southeast after sunset, stargazers can expect to see it illuminated against the evening sky. A lunar halo may also be visible around the moon due to ice crystals in Earth’s atmosphere—this phenomenon adds to its visual allure for astrophotography enthusiasts.

In terms of frequency, a full moon typically occurs once every 29.5 days. There are expected to be a total of 13 full moons throughout 2026.

Experts suggest that observing this micromoon offers a unique opportunity for stargazing. The Flower Moon’s appearance coincides with optimal conditions for lunar photography, as it presents an ideal subject against the backdrop of spring blossoms.

According to astronomers, “Tonight’s Flower Moon will not be the only full moon we get in May.” This statement highlights the excitement surrounding celestial events during this month.

The ring known as a ‘lunar halo’ is caused by the refraction of moonlight through ice crystals in Earth’s upper atmosphere. This natural spectacle adds an ethereal quality to the viewing experience.

The Flower Moon is named for the spring flowers that bloom in May. It occurs approximately every 29.5 days, marking the lunar cycle. This year, both full moons in May are classified as micromoons, meaning they will appear smaller and less bright than regular full moons.

Key lunar events in May 2026:

• The Flower Moon rises on May 1 at 20:46 local time in London.
• The Blue Moon occurs on May 31 at 4:45 a.m. ET.
• A full moon reaches its peak brightness when it is on the opposite side of Earth from the Sun.

During these events, the Moon may exhibit Earthshine—an illumination effect caused by sunlight reflecting off Earth’s surface. Additionally, viewers might observe atmospheric phenomena like a lunar halo, which can occur due to ice crystals in the atmosphere.

For those interested in stargazing, these full moons present an excellent opportunity for astrophotography. The Flower Moon’s visibility will extend past midnight into early Saturday morning, providing ample time for enthusiasts to capture stunning images.

However, officials have not confirmed whether any additional lunar events will coincide with these full moons. Observers should prepare for clear skies to fully appreciate this celestial spectacle.
