The August supermoon, also known as the sturgeon moon, occurs when the distance from the Moon to the Earth is only about 90% of normal.
This makes it a a “super moon” and this is also the last time a super moon will appear in 2022 according to retired NASA astrophysicist Fred Espanak.
Previous We have witnessed a total of 3 super moons taking place this year in May, June and July respectively.
According to Professor Sara Russell from the American Museum of Natural History, the phenomenon Super moons only occur when the Moon is in its closest orbit to the Earth, usually lasting from 2 to 5 full moons. This is also the reason why many super moons occur consecutively during the year.
The characteristics of super moons are that they are about 14% larger and 30% brighter than regular full moons. The reason is that when the Moon is closer, they reflect more light brighter than the Earth.
In theory, a full moon only lasts for a moment, but using normal observation methods, before and after that time is also considered a full moon. partly because the shadow due to obscuration is very narrow and changes so slowly that it is difficult for the naked eye to recognize.
It is worth noting that this year’s supermoon coincides with the peak phase of the Perseid meteor shower – one of the two largest meteor showers of the year.
This astronomical phenomenon originates from comet Swift-Tuttle discovered in 1862 and appears in the sky regularly from July 17 to August 24 every year, reaching its peak on the night of August 12 and early morning of August 13 with a maximum frequency that can reach 60-80 ice streaks/hour.
Because Why is it called “Sturgeon Moon”?
According to Live Science this name was first mentioned in the book Farmer’s Almanac published in 1818. Here, each full moon of the year is associated with a certain activity by Native Americans to facilitate determining the time.
The full moon in August is called the “full moon”. sturgeon” because it is associated with the sturgeon fishing activities of the Algonquin tribe in eastern North America, which only takes place during this special bright moon.
In Vietnam, superlatives can be observed. moon?
Because it takes place on the morning of August 12th and the influence of tropical depression, observing the super moon in Vietnam will be very difficult.< /p>
We will likely have to wait nearly another year to observe this amazing astronomical phenomenon because the next supermoon is expected to take place on August 1, 2023.
However, in 2023 there will be four consecutive super moon cycles, similar to what astronomers predict in 2024. Even 2025 will have 3 consecutive super moons.
