According to NASA, the supermoon phenomenon officially occurred on the evening of March 9, but throughout the 3-day period from March 8 to the early morning of March 11, it was also the period when the moon was full.
The supermoon phenomenon occurs when the moon is within 90% of the Earth's approach points on the Moon's orbit. At this time, the moon becomes brighter and larger in the night sky. This phenomenon can be clearly observed when it is clear and there are no other environmental conditions that obscure the view.
The full moon of March of the year is often called the full worm moon. This is a traditional name and is given by native Americans for each moon season in the year to help them track the seasons. According to the farmer's calendar, the worm moon in March is the time when the land starts to soften so that earthworms can appear, leading to many other birds to earn food.
According to CNN, the full moon has many other names, including the crow moon, crust moon, phallop month, Lenten moon and sugar moon, mainly used to report the upcoming spring months or in the case of the Lunar New Year, which is used to report the Christmas season of the Catholics.
Normally, there are full moon phenomena every 12 months of the year, but in November 2020, there will be 2 full moon phenomena, once on October 1 and the other on October 31.
Two full moons in the same month are called the green moon. In fact, the second full moon of November 2020 falls on Halloween, making the event even more special.
This year, according to CNN, there will be a total of 4 supermoons. After the supermoon on March 9, the next time an astronomer will witness the biggest and brightest moon phenomenon of the year on the night of April 7 and early morning of April 8.
According to Forbes, to observe the supermoon phenomenon on the night of March 9, American astronomers note that the moon will be brightest at night, located near the eastern horizon. In Europe and Africa, maximum brightness occurs around midnight.
Meanwhile, in Australia and Asia - including Vietnam, the supermoon will reach its peak brightness around the morning of March 10 in the western sky.
