The last supermoon of 2024, also called a 'cold moon,' will be visible across France and Quebec from December 4th to 5th, offering a spectacular astronomical event. The moon will be 8% larger and 15% brighter than usual as it reaches the perigee, its closest point to Earth at approximately 356,000 kilometers, compared to an average of 384,000 km. This supermoon coincides with a lunar cycle that lasts about 18 years, making it particularly high in the sky and exceptionally impressive. The event is rare, with the last similar phenomenon occurring in December 2006, and the next not expected until 2042. The moon will appear very high in the sky, reaching over 72 degrees in declination, and will be visible from sunset until late at night, with the best viewing time around 00:14 local time. Due to its proximity and position, the supermoon will be especially bright and photogenic, illuminating winter landscapes and possibly creating halos or other atmospheric effects. Temperatures during the night are expected to drop below -15°C across much of Quebec, adding to the 'cold moon' theme. Experts recommend viewing from a clear, dark location with minimal light pollution to fully enjoy the spectacle.
