Global Blue Moon Micromoon Lights Up Landmarks Worldwide

On May 31 2026 a rare celestial convergence occurred: a Blue Moon—the second full moon in a calendar month—coincided with a micromoon, when the Moon was at apogee, making it the smallest full moon of the year. The event was visible across the globe and illuminated numerous historic and cultural sites. In Greece the Moon rose behind the ancient Temple of Poseidon at Cape Sounio; in Egypt it bathed the Citadel of Saladin in Cairo; in Kuwait it shone over the city skyline. Photographers captured the Moon over the Eiffel Tower in Paris, the Statue of Liberty and Brooklyn Bridge in New York, the Bay Bridge and Alcatraz in San Francisco, the Sydney Opera House, and even over Chiang Mai in Thailand. Although called a “Blue Moon,” the Moon retained its normal pearly‑gray hue. The phenomenon recurs roughly every two to three years, with the next similar alignment not expected until 2053. One analysis noted that the spectacular sight drew large crowds to remote viewing spots, creating temporary pressures on local infrastructure and environmental management.
