Rare! The height of the full moon on July 3rd in various parts of China will be the lowest mid sky in 17 years | Horizon | China
According to the Guangzhou Wuyang Astronomy Forecast, the full moon on July 3rd this year will not only have the lowest ground level since the full moon, but also the lowest ground level since 2006.
In Guangzhou, the maximum altitude of the full moon on the horizon this time is only 39 degrees. Such a low full moon can only be seen a few times in a lifetime by even centenarians. At 19:39 on July 3rd this year, the moon, the earth, and the sun formed an approximate straight line. The moon is the roundest and also the closest moon to the earth this year. If the weather is clear, it can be seen all over China.
The moon has multiple cycles. For example, there are lunar periods such as synodic, stellar, and perihelial. There is also a less familiar "lunar ascending node westward retreat cycle", which has a length of 18.61 years. The height of the full moon's horizon around the world is related to this lunar cycle.
Experts say that the best time to observe the moon is at the midpoint of the local moon. During the mid day of the month, the moon is located in the due south direction, with the highest horizon height of the day, the brightest moon, and the best timing for observation.
In Mohe City, Heilongjiang Province, in the Arctic of China, the mid day of the full moon is 0:08 on July 4th, with the highest elevation of 9 degrees and the lowest in the country. In Beijing, at 0:33 on July 4th, during the upper and middle reaches of the moon, the maximum elevation of the full moon on the horizon is 22 degrees, which is 1 degree lower than the height at which the North Star can be seen in Guangzhou. In Shenzhen, at 0:43 on July 4th, the mid moon reached a maximum height of 40 degrees above the horizon.
What is the unique feature of Guangzhou's photography enthusiasts, as the height of the full moon is the lowest? Experts say that during the upcoming full moon, Guangzhou has had two consecutive opportunities to take photos of the full moon connecting directly to the Guangzhou Tower. The time of the mid month in Guangzhou is 23:41 on July 2nd and 0:46 on July 4th. The filming location is to the south of Guangzhou Tower, at the "Flower City Square" stone tablet in Tianhe District's Flower City Square. At that time, come to the "Flower City Square" stone tablet in advance, move forward or backward, and adjust to the point where the moon happens to pass by the top of the Guangzhou Tower, to take a photo of the full moon tightly connected to the Guangzhou Tower.
