Singapore will be graced with the second supermoon of the year on 18 September, just one day after the Mid-Autumn Festival, also known as the Mooncake Festival. Dubbed the Harvest Moon, it is the nearest full moon to the Autumn equinox in the Northern Hemisphere and marks the start of the fall season, according to the Science Centre Observatory (SCOB).
Background
The Harvest Moon is a significant astronomical event, particularly in the Northern Hemisphere, where it signals the beginning of autumn. Historically, the bright moonlight provided by the Harvest Moon aided farmers in harvesting their summer crops, hence its name. This year, the event coincides closely with the Mid-Autumn Festival, a cultural celebration that honours the harvest season and the beauty of the moon.
Viewing time
Singapore residents can expect to see the Harvest Moon rising at around 7:19 pm on 18 September. According to SCOB, it should be at an easily appreciable height from around 9:30 pm onwards.
Best viewing locations
As long as the skies are clear, the supermoon should be easily visible anywhere in Singapore without the need for any special equipment. The moon will be approximately 357,283 km away from Earth, according to EarthDate. For an unobstructed and potentially elevated view, public areas like the Marina Barrage, East Coast Park, and the Southern Ridges are recommended. However, the moon’s appearance can vary depending on atmospheric conditions and your specific location.
What is a supermoon?
A supermoon refers to a full moon that appears larger and brighter than usual. This phenomenon occurs when the moon’s orbit is closest to Earth, making it appear nearly six to seven per cent larger than usual. The Harvest Moon, specifically, is the nearest full moon to the Autumn equinox and marks the start of the fall season. According to SCOB, the supermoon earned its name because of the exceptionally bright moonlight it provides during this period.
Upcoming supermoons
If you miss the Harvest Moon, there will be two more opportunities to catch a supermoon this year. The next supermoons will occur on 17 October and 15 November, visible at distances ranging from 357,000 km to 361,000 km.
Cultural significance
The Mid-Autumn Festival, also known as the Moon Festival, holds great cultural significance in many Asian countries. This annual celebration brings families and communities together to honour the harvest season and appreciate the beauty of the moon. The festival is marked by various traditions, including the sharing of mooncakes, lantern displays, and family gatherings. The close timing of the Harvest Moon with the Mid-Autumn Festival this year adds an extra layer of cultural and astronomical significance to the event.
