Patna: Skywatchers are set for a striking celestial display tonight, as the final supermoon of 2025 – widely referred to as the Cold Supermoon – rises shortly after sunset. The December supermoon, associated with long, dark winter nights, is expected to appear significantly brighter and larger than usual.
Astronomy expert said the phenomenon will occur as the Moon reaches its closest point to Earth, known as perigee, at an estimated distance of 357,218km. “Because the Moon will be closer than usual, its apparent size and brightness will increase noticeably,” she said.
The supermoon will remain visible throughout the night without the need for telescopes or any special equipment. Observers in areas with minimal light pollution are likely to experience the most striking views. The effect is expected to be particularly dramatic around sunrise due to the “moon illusion”, which makes the Moon appear unusually large near the horizon.
In India, the moon will be visible soon after dusk, provided weather conditions are clear. Fog, mist or rainfall may reduce visibility in some regions. The spectacle will also be observable from cities including London, Edinburgh, Belfast and Cardiff.
Known as the Cold Moon or Long Night Moon due to its appearance during one of the darkest months of the year, the lunar disc is expected to shine at nearly 100% illumination. For many, it is seen as a symbolic seasonal marker – a luminous close to the year, lighting winter skies in silver.
