Panaji, May 31: Skywatchers in Goa are set to witness a rare celestial spectacle tonight as a ‘Micro Blue Moon’ appears in the night sky, offering a unique astronomical combination that occurs only infrequently.

According to the Association of Friends of Astronomy, Goa, the phenomenon brings together two distinct lunar events. A ‘Blue Moon’ refers to the second full moon occurring within a single calendar month, while a ‘Micro Moon’ is observed when a full moon coincides with the Moon being near its farthest point from Earth in its orbit, known as apogee.

Explaining the occurrence, association president Satish Nayak said the event represents a rare alignment, making the Moon appear slightly smaller than an average full moon. He noted that it is the opposite of a Supermoon, when the Moon appears larger due to its closest approach to Earth.

This year’s occurrence is also significant as it coincides with Adhik Jyeshtha Purnima, the full moon of the intercalary month in the traditional Indian lunar calendar, which appears once every few years. The convergence of these lunar and calendrical cycles makes the sighting particularly uncommon.

Astronomy enthusiasts say such combinations are rare and attract attention from observers and researchers alike. However, visibility may depend on weather conditions, with monsoon clouds expected to affect viewing chances in parts of Goa.

Experts said the phenomenon can be observed with the naked eye without the need for telescopes or specialised equipment, provided the sky remains clear during the night.
