The coastal state of Goa is set to experience a rare astronomical event on May 31, 2025, as a micro blue moon will grace the night sky. This phenomenon, which occurs only two to three times in a century, will make the moon appear slightly smaller than a typical full moon.
What is a Micro Blue Moon?
A blue moon is defined as the second full moon occurring within a single calendar month. A micro moon, on the other hand, is an astronomical phenomenon where the full moon appears smaller than usual because it is at the farthest point of its monthly orbit, known as apogee. This is the exact opposite of a supermoon, where the moon appears larger due to being at perigee.
Significance of the Event
This rare event coincides with the leap month of the Indian calendar, known as Ashok Jyeshtha Poornima, which occurs once every four years. The combination of a blue moon, a micro moon, and the leap month makes this a particularly unique occurrence.
Visibility and Weather Concerns
The visibility of the micro blue moon may be affected by the prevailing monsoon season and cloudy weather conditions in Goa. However, the moon will still be visible to the naked eye for those who manage to catch a glimpse between the clouds.
Astronomy enthusiasts and casual observers alike are encouraged to look up at the sky on May 31 to witness this rare celestial event. For those unable to see it in person, live streams and updates from local astronomical societies may be available.
