Rare Blue Microlune to Illuminate Sky This Sunday: What to Expect

This Sunday, observers will witness a rare astronomical event known as the Blue Microlune. This will be the second full moon of the month, which also marks a unique combination of celestial occurrences.
Understanding the Blue Microlune
The term “Blue Moon” refers to the second full moon within a calendar month. The first full moon of May, often referred to as the “Flower Moon,” appeared on May 1. Such occurrences happen approximately every 2 to 3 years, as noted by NASA.
Upcoming Lunar Events
- The last Blue Moon took place on August 19, 2024.
- This upcoming event will occur at its peak at 4:45 AM.
- The next Blue Moon is anticipated on May 20, 2027.
Characteristics of This Microlune
This Sunday’s full moon will coincide with its apogee, the point in its orbit where it is farthest from Earth. Consequently, it may appear 10 to 15 percent smaller than usual, according to National Geographic.
This phenomenon is what gives rise to the name “microlune.” Despite its name, the Blue Moon will not exhibit a bluish hue. Enthusiasts and photographers may wish to capture this lunar sight to compare its size with the upcoming Supermoon, which will occur at the moon’s perigee, its nearest point to Earth, on December 24, 2026.
