The world welcomes the last super moon of the year

According to AL, super moon appears about 4-6 times a year, but not every time comes with the full moon. The night of October 26 and today morning October 27 is the nearest full moon after the Fall of the Year, known as Hunter's Moon (Hunter's Moon). In Vietnam, the full moon will appear around 19h on October 27 , coinciding with the September full moon, according to Time and date.

According to Earth Sky, each full moon has its own name, related to the months of the year, or season, such as the Harvest Moon Moon and Hunter's Moon . Harvest Moon is the full moon closest to Falling time of the year, and Hunter's Moon is the full moon right after Harvest Moon.

For those who live in the Northern Hemisphere, the Fall of 2015 takes place on September 23. The full moon, which appeared on September 27, was Harvest Moon in the Northern Hemisphere, the entire lunar eclipse that night. So the full moon on October 26, 27 is Hunter's Moon. As soon as the Sun goes down, the Moon grows right at the horizon, it will shine in the sky from dusk and the brightest at midnight.

For Southern Hemisphere, the time of Falling distribution takes place in the middle of March every year. Therefore, information on Harvest Moon and Hunter's Moon in this article will apply to those who live here in March and April next year.

At the Northern Hemisphere, Harvest Moon usually falls in September or October, so Hunter's Moon will occur in October or November. The Moon will average about 50 minutes later than the previous day. But when the full moon appears close to Falling Fall, it can be Harvest Moon or Hunter's Moon, it will only grow 30 to 35 minutes later than the previous day.

The reason is that the zodiacal plane, or the orbit of the Moon, forms a narrow angle compared to the evening horizon during the Falling time. This makes the time when the Moon grows in the following days, close to Hunter's Moon, becomes shorter.

After Hunter's Moon happens, at the North latitude we will see the Moon rising higher in the East, and appear earlier on a straight line after the Sun goes down.

Hunter's moon is just a full moon. However, many people think it looks bigger, brighter and more orange than usual. The reason is that it grows near the horizon, the light coming from the Moon must pass through the thicker atmosphere on Earth than it was at the top of the head.

Light with short wavelengths such as blue or violet is almost scattered by the atmosphere, only the light with a long red-orange wavelength reaches the observer's eye (the shorter the wavelength of light, the stronger the ). Therefore, the full moon growing near the horizon will be yellow, orange or reddish. At this point, the Moon looks bigger than not because it is bigger, but because of the Moon Illusion effect.

Most of the time when Hunter's Moon happens, the Moon is not brighter than usual. However, 2015 is an exception because it is close to the time of the super moon.It is not until October next year that we can see this phenomenon again.

Super moon occurs because the Moon orbits the Earth in an elliptical orbit, with an average distance of 384,000km. The farthest position of the Moon compared to Earth is 405,600km apart, the closest position (near point) is 363,700km apart. Super moon is the full moon at the near-point position, 14% larger and 30% brighter than when it is at the farthest position, also known as "minimoons".

The Moon moves to the point on October 26, less than 24 hours before the full moon. Today, people also call the near-full moon times as super moon. The size and brightness of a super moon depends on the location of the observer. The moon tonight will be bigger and brighter than the 27th.

So where does Harvest Moon and Hunter's Moon come from? In each fall, the dark time appears quite short between the setting sun and the rising moon for many consecutive days around the time of the full moon. In the absence of lights, the moon light helped farmers harvest crops (Harvest Moon). As the sunlight fades to the west, the Moon will rise in the east to light the field all night.

One month after the harvest is complete, the light of the full moon (Hunter's Moon) will illuminate the prey on the remaining straw stubble in the field, and is the ideal time to hunt. Therefore, the names Harvest Moon and Hunter's Moon can be derived from this tradition.
