What is a Supermoon?
On Wednesday night, sky gazers will have the opportunity to witness the second supermoon of the year. Dr. Sara Webb, an astrophysicist at Swinburne University in Melbourne, explains that a supermoon occurs when the moon’s orbit is closest to Earth while it is full. This phenomenon results in the moon appearing bigger and brighter than usual. The upcoming supermoon will be approximately 357,000km from Earth, which is 27,000km closer than its average distance. With this significant proximity, the supermoon is sure to captivate observers with its luminous presence.
Where and When to View the Supermoon
For those eager to catch a glimpse of the supermoon, it is best viewed as it rises above the horizon. Dr. Webb suggests finding a dark location that faces east, where the moon will make its ascent. In Sydney and Melbourne, the supermoon will rise around 6pm, while viewers in London and New York can expect it at 7pm. On the US west coast, the moon will rise at 7:30pm. Ideal viewing spots on the east coast of Australia include Brisbane and Sydney, offering prime vantage points for the celestial event. Dr. Bradley Tucker from the Australian National University recommends flat locations such as the US east coast or central Australia for a spectacular view of the rising supermoon.
To fully appreciate the supermoon’s grandeur, it is advisable to avoid areas crowded with buildings. As the moon climbs higher in the sky, it may start to resemble a typical full moon. The supermoon will reach its highest point and peak fullness around half past midnight in Australia and just after 10:30pm on the US east coast. If you happen to miss this supermoon, fret not, as two more are scheduled to occur on October 17th and November 15th this year.
The Supermoon Eclipse and Lunar Phenomena
In addition to the supermoon, a partial lunar eclipse is set to take place on Wednesday. Unfortunately, this celestial event will not be visible from Australia, with optimal viewing locations in South America, west Africa, and western Europe. Dr. Webb explains that the eclipse coincides with the moon being on the opposite side of the Earth during Australian daytime, making it out of sight for observers in the region. While a partial eclipse signifies a slight misalignment of the sun, moon, and Earth, it remains a noteworthy occurrence.
Dr. Webb further elaborates on the fascinating phenomenon of lunar and solar eclipses, describing them as chance alignments of the Earth, sun, and moon. A full lunar eclipse, often referred to as a blood moon, is one of the most remarkable lunar events. While the partial eclipse may not be visible from Australia, it serves as a reminder of the intricate dance of celestial bodies in our solar system.
The Harvest Moon, as September’s supermoon is known in the US, holds cultural significance tied to the autumn harvest. Dr. Tucker explains that the naming of the moon each month is rooted in historical and cultural traditions, reflecting seasonal changes and agricultural practices. While the Harvest Moon may not align with the southern hemisphere’s seasons, it serves as a reminder of the interconnectedness of celestial events and human activities on Earth.
