According to Guangzhou Wuyang Planetarium revealed: At midnight on July 14th, the largest super moon that will occur this year will be visible to all parts of China. The best observation time is from the night of July 13th to midnight on July 14th. This year's super moon (child's full moon) will be the child's full moon with the lowest altitude in the northern hemisphere since 2008.

A super moon refers to a child's full moon at "perigee". Now at 17:06 on July 13, the moon moves to the nearest "perigee" of the earth, which is only 357,372 kilometers away. At this time, the moon's visual aperture is larger; at 2:38 on the 14th (look), the moon and the earth Arranged in a straight line similar to the sun, the moon is at its roundest at this time, and the moon's apparent aperture reaches 33.7 arc minutes, which is larger than the annual apparent aperture of the sun.

Observation shows that for the same child's full moon, the visual aperture of the child's full moon is 14% larger at the "perigee" than at the "apogee", and the visual area is 30% larger.

In Guangzhou, at 19:06 on July 13, the moon will suddenly fly from the horizon in the south-eastern part of China; at 0:30 the next day, the moon will be at the zenith, located due south, with a relatively high altitude of 41 Spend. At 2:38, the ecliptic longitude of the moon and the sun are 180 degrees apart, and the moon is at its fullest at this time; at 5:56, the moon faintly sets from the southern horizon of Western countries.

When the super moon rises in the east, people will feel that the full moon is very big and looks golden. At this time, you can use your mobile phone or digital camera to take photos with the super moon, usually with a flash.

html The supermoon on July 14th was the lowest full moon in the past 14 years when the moon was at its zenith. The zenith of the moon and the horizon around the country: Harbin at 23:35 on July 13, 18 degrees; Beijing at 0:17 on July 14, at 24 degrees; Shanghai at 23:56 on July 13, at 33 degrees; Guangzhou At 0:30 on July 14, the temperature was 41 degrees; at 0:27 on July 14, the temperature was 42 degrees in Shenzhen; and in Haikou City, the temperature was 44 degrees at 0:43 on July 14.

Under normal circumstances, a super moon will occur once every 14 synodic months (about 413.4 days). The next supermoon will occur on August 31, 2022. At that time, the moon will pass the "perigee", which is only 357,181 kilometers away, and can be seen all over China. Next year's supermoon will have a higher apparent aperture than this year's supermoon.
