In the three days from today, the weather in our city has gradually improved, and the weather is warm and comfortable. Today, a partial lunar eclipse that is almost a total eclipse will be staged in Tianyu, and interested citizens should not miss it.
The lowest temperature at the National Basic Weather Station in Xiamen was 18.2℃ in the early morning yesterday and rose to 21.9℃ in the afternoon. The weather station with the highest temperature in the city is located in Siming Tuyu, with a maximum temperature of 25.2℃. Yesterday, there was sporadic light rain in most areas of Xiamen, with rainfall within 1 mm, relative humidity above 65% throughout the day, and humid air.
Before a new burst of cold air arrives, the weather in our city is good. For three days from today, the rain stopped, the weather was cloudy, the lowest temperature was between 17°C and 18°C, and the highest temperature rose back to 24°C to 25°C. The northeast wind is strong, but it is warm and comfortable.
With the increase of cold air troops going south, our city will usher in a process of strong wind cooling. The influence of cold air is expected to drop to 18°C from the 22nd to the 24th. The extreme lowest temperature during this process occurred in the early morning of the 24th, and the lowest temperature was 12°C. During the period of cold air, there will be strong northeast winds of magnitude 6-8 in our city. In addition, on the 22nd, there may be light showers in our city, and citizens should take precautions.
According to Xinhua News Agency, today’s partial lunar eclipse ushered in its initial loss at 15:18 Beijing time, with a heavy eclipse at 17:03 and a return at 18:47, which lasted 3 hours and 29 minutes. When the lunar eclipse occurs, most areas of our country are in the eclipse range, that is, when the moon rises above the horizon, it happens to be in the partial lunar eclipse phase.
Senior astrophotography enthusiast Wang Junfeng said that compared with solar eclipses, lunar eclipses are relatively easy to observe and photograph. The lunar eclipse is not bright, lasts a long time, and covers a large area. You only need to be in a place where the moon can be seen when observing.
Wang Junfeng said that if you want to take a stunning “quasi-red moon”, it is first recommended to use a SLR or mirrorless camera with a telephoto lens to get close-ups of the lunar eclipse at various time periods, and then you can use the middle focal length to shoot, or use a wide-angle lens to shoot the month. The “string image” of the eclipse process; in the case of a small astronomical telescope, it is also a good choice to connect the camera body or mobile phone camera to the telescope eyepiece through a clamp or an adapter ring. In addition, the current major mainstream mobile phones can also easily capture the lunar eclipse. A single photo can be taken in automatic mode or night scene mode. It is recommended to use the middle focal length (generally 3X or 5X) to shoot the real video or time-lapse video. When shooting, it is best to choose some unique landscapes, such as high towers, ancient buildings, bridges, etc., so that the photos taken are more ornamental.

Why is there a lunar eclipse
When viewed from the earth, when the sun and the moon are just in the opposite position, the shadow of the earth will sweep across the moon, temporarily blocking the sun’s light and darkening the moon, thus forming a lunar eclipse.
The phenomenon of “not round” the moon usually sees is not a lunar eclipse, but a “missing”, which is a normal phase of the moon.
In the complete process of a lunar eclipse, the moon will go from round to missing and then round in one night. The lunar eclipse must occur on the night of “Wang” (full moon).
A complete phase cycle of the moon is approximately 29.5 days, which is a lunar month. It stands to reason that there should be a lunar eclipse every lunar month. It is a pity that the moon’s orbit around the earth (white track) and the earth’s orbit around the sun (ecliptic) are not on the same plane, but have an intersection angle of about 5°. A solar or lunar eclipse can only occur when the sun and the moon are located near the two “yellow and white nodes”.
Globally, solar eclipses can occur up to 5 times a year, such as in 1935; at least two solar eclipses can occur, such as in 2017. In some years, there is no lunar eclipse, such as 1980; there are 4 times at most, such as 2020.
A total of 7 solar and lunar eclipses can occur in a year: one is 5 solar eclipses and 2 lunar eclipses, such as 1935; the other is 4 solar eclipses and 3 lunar eclipses, such as 1982. The most common occurrence is 2 solar eclipses and 2 lunar eclipses, as in 2015.
