Stargazers across India are in for a celestial treat as the final supermoon of the year 2025 prepares to cast its brilliant glow on the night of Thursday, December 4. This astronomical event promises a spectacularly large and luminous full moon, offering a perfect opportunity for skywatchers to witness one of nature's most captivating displays.
What Makes This December Moon a Supermoon?
Unlike an ordinary full moon, a supermoon occurs under a specific cosmic alignment. The phenomenon happens when the moon reaches its closest orbital point to Earth, known as perigee, at the same time it is in its full moon phase. This dual coincidence results in the moon appearing significantly larger and brighter from our perspective on Earth.
Scientists refer to this precise alignment as 'syzygy-perigee'. For enthusiasts and casual observers, however, it translates to a simple yet stunning visual effect: the lunar disc can look up to 14% larger and noticeably brighter compared to a regular full moon, especially when it is near the horizon.
Goa's Supermoon Schedule and Viewing Details
For residents and visitors in Goa, the viewing conditions are set to be ideal. The supermoon will make its evening debut at 5:22 PM on December 4. It will then journey across the night sky, remaining visible until it sets at 5:50 AM on December 5. This long visibility window provides ample time for observation and photography.
To make this event accessible to all, the Association of Friends of Astronomy Goa has organized a series of free public observation sessions. These gatherings require no prior registration or fee, inviting everyone to partake in the experience.
Public Observation Locations Across Goa
The association has set up multiple vantage points for the community. The primary locations include:
- Panaji: The public astronomical observatory at Junta House.
- Mapusa: The grounds of Saraswat College in Khorlim.
- Benaulim Beach: For a scenic seaside view of the moonrise.
- Baina Beach: Another coastal location for unobstructed horizons.
- Porvorim: The Art Park will also host a viewing session.
These organized events are an excellent way for beginners to learn from experienced astronomers and use telescopes for a closer look at the lunar surface.
A Grand Finale to the Year's Lunar Calendar
The December 4 supermoon serves as the grand finale for the year's notable lunar events. Its occurrence during the pleasant winter skies of Goa enhances the viewing experience, with typically clearer atmospheric conditions. Such events not only foster public interest in science and astronomy but also create shared community experiences under the night sky.
Whether you join one of the organized sessions or simply step out into your backyard, remember to look up on the evening of December 4. The last supermoon of 2025 is poised to deliver a memorable and brilliant performance, marking a beautiful end to the year's celestial calendar.
