Can the red moon see?

On June 8, 2022, there will be a rare red moon (total lunar eclipse). If the weather is clear, it can be observed in most parts of China, and the observation conditions in the eastern region are better than those in the western region. The day is around 19, which is most suitable for viewing the red moon. On that day, the earliest city in China was Fuyuan, Heilongjiang Province. Fuyuan Moon/KLOC-rises at 0/5: 24, and the local public is expected to see the beauty of the red moon first.

The red moon

Because the moon orbits the earth from west to east, the eastern edge of the moon enters the shadow first. Because sunlight has seven colors of "red, orange, yellow, green, cyan, blue and purple", the first three are "warm colors", and the wavelength of red light is the longest, which can penetrate the dense atmosphere and refract and scatter to the space of the Earth's umbra.

Therefore, even when the moon enters the umbra of the earth, the public can still witness the "bronze color" of the moon, which is called the "red moon".

The process of the red moon

The red moon can be divided into seven stages. The total lunar eclipse is at 1 1.08, and the penumbral eclipse begins at 16: 08+0 (the moon begins to touch the penumbra of the earth); Initial loss 17: 09 (the moon just touches the umbra of the earth); 16 at solar eclipse 18 (the moon just entered the umbra of the earth); The eclipse is 18: 59 (the center of the moon is closest to the shadow center), and the maximum eclipse is 1.364.

Light is 19: 42 (the moment when the moon appears from the umbra of the earth); The last contact was at 20: 49 (the moon was just completely out of the umbra of the earth); The penumbral eclipse ends at 2 1: 58 (the moon has just completely separated from the penumbra of the earth). The whole red moon lasts 1 hour for 26 minutes (from food to light).
