Rare Blue Moon & Micromoon Align!
30 May
Summary
- A Blue Moon is the second full moon within a calendar month.
- This rare event occurs every two to three years.
- The May 2026 Blue Moon is also a micromoon, appearing smaller.
Skywatchers are in for a celestial treat as a rare Blue Moon illuminates the night sky this weekend, May 30-31, 2026. This infrequent event, occurring approximately every two to three years, will be observable across the globe, including India.
Contrary to its name, a Blue Moon does not appear blue; it signifies the second full moon within a single calendar month due to the slight difference between lunar cycles and calendar months. This year's occurrence is particularly noteworthy as it coincides with a micromoon.
A micromoon happens when a full moon occurs near the Moon's farthest orbital point from Earth. Consequently, the May 2026 Blue Moon will appear slightly smaller and less bright than a typical full moon. Despite this subtle difference, the event promises a spectacular view, especially during moonrise.
People in India can witness this phenomenon on the evening of May 30. The Moon is expected to appear larger and have a warm orange glow near the horizon due to atmospheric light scattering, shifting to its familiar bright white as it ascends. Clear skies and an unobstructed view will enhance the experience.
