On the evening of May 26, the "total lunar eclipse" will be superimposed with the "supermoon" to form a rare "super red moon".
Where in our country can you see the "super red moon"? According to the China Meteorological Administration, in addition to western Tibet and western Xinjiang, other regions can see "bringing food out", and the further east the region, the more complete the lunar eclipse seen, the longer the duration of the total eclipse.

According to astronomers, when the position of the moon, the earth, and the sun in the universe is in a straight line, the shadow of the earth blocks the moon, and a lunar eclipse will occur. Coincidentally, this total lunar eclipse is also the largest moon in this year's full moon, which can be said to be a "supermoon" that rises with eclipse.
At the same time, the moon will also "change color", that is, when the moon fully enters the earth's umbra, because the sunlight is refracted and scattered by the earth's atmosphere, only a small amount of red-yellow light with a longer wavelength can penetrate the atmosphere and shine on the moon, so that the public can see a round of "blood-colored" moon in the total eclipse stage.
However, it is worth noting that the distance of the moon through the shadow of the earth is short, resulting in a shorter duration of total eclipse, from eclipse to light is only 20 minutes. Specifically, the lunar eclipse will begin at 17:45 Beijing time on May 26, when the lunar surface begins to lose (initial loss). By 19:09, the Moon was fully in the shadow of the Earth (eclipse), reaching maximum occlusion (eclipse) at 19:19. At 19:28, the moon began to glow again (raw light), at 20:53 the moon came out of the shadow of the earth (polycyclical); at 21:51, the total lunar eclipse ended, and the full moon returned to its former smoothness.
During a total eclipse, the moon does not disappear in people's sight, but takes on a mysterious and elegant bronze color, which is what people see as the "red moon".
Want to have a "one-sided relationship" with super red moon? Zhang Feng, deputy chief forecaster of the National Meteorological Center, said that on May 26, the weather conditions in northern Xinjiang, Hexi region of Gansu, western Inner Mongolia, Ningxia, northern Shaanxi and other places in China will be more conducive to moon appreciation.
Although the weather conditions in North China, including Shanxi and Beijing-Tianjin-Hebei, are also more suitable, there may be showers in some parts of these provinces and cities on the evening of the 26th, which will affect the viewing;
In addition, on the day of the 26th, affected by the high-altitude trough and the low-layer shear line, a new round of precipitation process will affect the southern region of China, bringing a wide range of rainy weather, and the precipitation is mainly concentrated in the evening to night of the day. It is expected that on the 26th, parts of the eastern Part of Jianghan, Jianghuai, north-central Jiangnan, and southern Guizhou will have heavy to heavy rain and local heavy rain. The "Super Red Moon" will be difficult to see in the above areas. At the same time, there will also be rainy weather in the northeast region of China that day, and the cloud cover above the sky will be relatively large at night, which is difficult to see.

It should be noted that on the 26th, for the above-mentioned areas suitable for moon viewing, it will be affected by a weak cold air, and the temperature will drop by 4-6 °C. At the same time, in the afternoon of the 26th, in Ningxia, northern Shaanxi, Shanxi and western Inner Mongolia and other places there are 5-6 winds, gusts in some areas up to 7-8 or more, although the wind will decline at night, but in the outdoor moon viewing or pay attention to away from some structures that are easy to be blown by the wind, and pay attention to adding clothes.
How to observe this astronomical wonder smoothly? China Weather Network recommends three viewing methods:
(1) Naked eye viewing: This lunar eclipse is a "super total lunar eclipse", and the moon is red and large. Coupled with the proximity to the horizon, there is a landscape contrast, visually beautiful, so the naked eye can see.
(2) Observation with binoculars: If you use binoculars, astronomical telescopes and other equipment to watch, the effect is better. Binoculars have a large field of view, easy to carry and easy to operate. For the moon, the magnification of magnification is also just right, you can put the entire picture of the moon into the field of view, so it is a powerful auxiliary observation tool for watching the total eclipse of the moon. The specifications can be selected for binoculars with magnification of 7 to 10 times, objective diameters of 35 mm to 50 mm, and field of view of about 8°.
(3) Observation with astronomical telescopes: Astronomical telescopes can enlarge the moon by dozens of times, which can significantly increase the brightness of the moon and see the details of the moon more clearly. At the same time, it is possible to see the characteristics of landforms such as the moon sea, craters, and mountains. If you can connect the camera behind the telescope, you can also take a beautiful close-up photo of the lunar eclipse.
