China News Service, Guangzhou, September 27th (Guo Jun and Li Jianji) According to the Guangzhou Wuyang Planetarium, this year's National Day Mid-Autumn Festival has a happy meeting, and there are many specialties.

During the Mid-Autumn Festival and National Day holiday this year, the fullest moon appeared at 5:05 on October 2 and was visible in most parts of China.

This will be the roundest Mid-Autumn Moon that China has seen since 2017.

　　Experts say that the Mid-Autumn Festival and National Day appear on the same day, and this special phenomenon of astronomy and calendar is very rare.

In the 20th century, it appeared only once (1982); in the 21st century, it appeared only four times (2001, 2020, 2031, and 2077).

　　"The moon of fifteen and sixteen rounds."

From statistics, it is found that the moon is the roundest and appears the most on the 16th lunar calendar, followed by the 15th lunar calendar.

In the last 3 years (2018-2020), the moon is the roundest on August 16 of the lunar calendar.

In the next 3 years (2021-2023), the moon will be the roundest on the 15th of the eighth lunar month.

　　At 1 o'clock on October 4 this year, the moon was farthest from the earth, about 405,294 kilometers.

Therefore, during the Mid-Autumn Festival, the apparent diameter of the moon is not only smaller than usual, but also smaller than the apparent diameter of the sun that day.

But compared with last year, this year's Mid-Autumn Festival moon is slightly larger than last year, because last year's Mid-Autumn Festival and the moon were the furthest away from the earth and happened on the same day.

　　It is reported that since 2013, on the night of this year's Mid-Autumn Festival, all parts of the country will go to the sky at the latest.

Among them, the moon transit in Guangzhou was at 0:16 on October 2, which was the latest moon transit in Guangzhou in seven years.

What are the characteristics of Moon Sun Zhongtian?

The moon will rise to its highest on the night of the Mid-Autumn Festival, the thinnest atmosphere through the moon, and the brightest moon, which is the best time to enjoy the moon; secondly, the moon is also located in the south direction, becoming a veritable "compass".

　　During the Mid-Autumn Festival this year (September 30-October 2), Guangzhou (East longitude 113 degrees 16 minutes) three consecutive days of moon transit time: September 30, 23:35 (new moon night), moon height 60 degrees; at 0:16 on October 2 (moon viewing night), the moon height is 65 degrees; at 0:56 on October 3 (moon night), the moon height is 70 degrees.
