Yes, tonight, May 31, 2026, is a full moon. This particular full moon is rare, as it is both a Blue Moon and a micromoon. The moon reached peak illumination earlier today at 4:45 a.m. EDT. It will remain 100% illuminated throughout tonight, offering excellent viewing opportunities.
Key Characteristics of Tonight's Moon • Blue Moon: This is the second full moon in the month of May 2026, following the "Flower Moon" on May 1.
• Micromoon: The moon is currently at its farthest point from Earth, making it appear roughly 14% smaller and 30% dimmer than a supermoon.
• Astronomical Neighbors: You may be able to spot the bright red star Antares glowing nearby in the constellation Scorpius.
• Next Occurrence: While blue moons happen every 2–3 years, the next blue micromoon will not occur until May 2053.
Viewing Tips • Moonrise: Check the Time and Date Moonrise Tracker
for exact times in your specific city.
• Best Locations: Find an open area with a clear view of the eastern horizon shortly after sunset.
• Equipment: While visible to the naked eye, binoculars can help you see specific features like the Tycho Crater or the Grimaldi Basin.
