A blue moon will peak today at approximately 9:45 AM, marking a rare astronomical event. This month has already featured a full flower moon, which was notable for being a micromoon, appearing smaller and dimmer in the sky. The current blue moon is also classified as a micromoon, adding to its uniqueness. Traditionally, a blue moon refers to the occurrence of a 13th full moon in a calendar year, a phenomenon that arises due to the lunar cycle not aligning perfectly with the calendar year. While the term suggests a color, blue moons appear just like any other full moon.
Why It Matters
Blue moons take place about every two to three years, with the last one occurring on August 19, 2024, and the next expected on May 20, 2027. The concept of a blue moon has historical roots in lunar naming conventions and has been popularized through various cultural references. There are two definitions for blue moons: the traditional 13th full moon in a year and the second full moon in a single month. The occurrence of a blue moon serves as a reminder of the complexities of the lunar calendar and its relationship with our own calendar system.
