How did the eclipse of 20 18 1 3 1 come into being?

A total lunar eclipse will occur on June 365438+1October 3 1 and June 20 124, including Asia, Oceania, Europe and North America.

This eclipse begins at 18+0, 20 1, and the time is 18: 50. At this time, the moon moves to the penumbra of the earth, and the surface of the moon gradually becomes slightly darker from the east. 19: 48, the moon began to enter the umbra of the earth, and the missing angle began to appear on the east side; At 20: 5 1, the surface of the moon completely entered the Earth's umbra, and after 2 1: 30, it was the deepest shadow of the solar eclipse, and it gradually separated from the Earth's umbra at 22: 08. From 20: 5 1 to 22: 08, it is the most essential total eclipse stage of this eclipse, totaling 6554.

In the stage of total lunar eclipse, the lunar surface covered by the earth's shadow is still illuminated by some red sunlight refracted by the earth's atmosphere, so the lunar surface of total lunar eclipse is dark red; After the birth of light, the moon's white and bright edge began to appear in the southeast. By the last contact at 23: 12, the moon's missing angle disappeared and returned to the shape of a full moon. However, because the moon is still in the penumbra, the west of the moon is slightly darker to the north. 1 February, 0: 10, the penumbral eclipse ended, and the moon left the penumbral of the earth, ending the eclipse.

The whole process lasted 5 hours and 20 minutes.

Sunlight is refracted by the earth's atmosphere, so there is red light that will shine on the surface of the moon.

In this way, we can still see a red moon in the middle of the total lunar eclipse.

If the weather is clear, this "red moon" will be very obvious.

"Blue Moon" certainly does not describe the color of the moon.

"blue moon" literally translates from English "Blue Moon", which means "rare thing".

In astronomy, the "blue moon" is the second full moon in a month. Because it is rare, it is called "blue moon".

"Super moon" refers to the "chubby figure" of the moon.

When this "blue moon" happened, the moon was just near the perigee. Seen from the earth with naked eyes, the moon looks bigger than usual.

The "blue moon" is not uncommon, but if the "blue moon" is a "super moon" and a total lunar eclipse occurs at the same time, it is a very rare astronomical phenomenon.

The "super moon" and the total lunar eclipse appeared together, only five times in the 20th century, and the last appearance of this phenomenon can be traced back to1March 3, 8661.
