At night, there is a light in the northwest direction of the sky, what is going on?

First determine whether you are in the Southern Hemisphere or the Northern Hemisphere, if you are in the Northern Hemisphere then you can determine the North according to the North Star, the way to determine the position of the North Star is (first find the constellation Ursa Major "also known as the Big Dipper", which is the standard length of the two stars of the spoon handle, and the "standard length" of 5 times the direction of the spoon handle is the exact position of the North Star.

If you're in the Southern Hemisphere, you're looking for the Southern Cross

It's easy to find a cross made up of 5 stars, and you can basically find it in a circle. The 3 stars in the middle refer to the south, but not very positive

Aim for the North Star. First of all, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by 5 times, and then you can find the North Star in this straight line, and the direction of the North Star is due north.

The constellation of the Southern Cross, near the South Celestial Pole, is composed of four bright stars, shaped like the character "ten", called the Cross Star in China, and is the main basis for judging the direction at night in the Southern Hemisphere. In areas south of 23°N, the Southern Cross constellation can be used to determine the orientation in the first half of the year. The constellation of the Southern Cross, the two stars is the famous first-magnitude bright star in the southern sky, which is the second-magnitude bright star, which extends the line with the two stars in the direction of to, about four times the distance between the two stars, that is, the southern celestial pole, that is, due south.

The Centaur constellation and the two stars on the east side of the Southern Cross constellation are both first-class bright stars in the southern sky, and the perpendicular line that connects with and the two stars also points due south.

There are high-ranking imperial weapons flying through the sky!

How do I know what!

Jupiter The bright star that looks southeast in the first half of the night is Jupiter, with an apparent magnitude of -two. Wait a minute, you can look at the Vega and the Cowherd at the zenith, compared to Jupiter. The Weaver Girl is the third class.

At about 2 o'clock in the second half of the night, a few bright stars in the constellation Orion could be seen due east, as well as Sirius below Orion. Sirius-one. Four continents and so on, less than half the brightness of Jupiter.

The light effect, there are two strong beams of light shining into the sky, and the place where the light shines is shining, so it is thought that the clouds are moving. I'm Jack Lee.

It is the clouds that move with the movement of the air, and we see it as if the clouds are in the east of the clouds, but in fact they are not on the same plane, they are far away.

I also saw it tonight, at first there were three clusters of red, then only two, and the color became lighter and lighter, basically moving back and forth in the same position.

I also saw that on October 5th, there were 6, 1 was the center, 5 were circled, and then they were gathered together, separated by more than ten seconds, and in concentration, lasting 1 hour. I haven't seen it for a few days.

It could be high-altitude ball lightning.

I used to see it when I was a kid, it lasted for a few nights, and then I never saw it again.

When I was a child, I used to see that if you took a flashlight and swayed it in the sky at night, it would attract the attention of a flying saucer, but now that the standard of living has improved, the flashlight has been replaced with a searchlight. Got it?

A long-range spotlight installed on tall buildings that serves as a warning to flying objects in the air, as well as a decorative effect.

That's ordinary visible light, not any special light

There are a large number of tiny particles suspended in the atmosphere, and when the light is illuminated, the Tyndall phenomenon is produced due to the reflection of the particles to the light. In the case of a point light source, the light is emitted in a spherical shape, and the lamppost cannot be seen.

The movement of clouds affected by changes in upper-air currents should be normal and nothing mysterious.

Upper-air flow map, i.e., a map that depicts the average airflow conditions at a certain height or layer at a certain altitude in the upper air. It is divided into two types: contour and isobaric surface. The former was more popular in the early days, generally representing the air pressure system on the 5000-meter contour plane, including air flow lines, high-pressure axes, low-pressure trough lines, shear lines, equatorial convergence lines, anticyclones, cyclones, etc.

The latter is now widely used and is usually used to express height, humidity, temperature, and streamline fields on isobaric surfaces of 500 mbar.

During the First World War, some countries attached great importance to future weather forecasting, and they jointly carried out upper-air observations three times a day, using upper-air flow maps to forecast upper-air wind conditions in North America and Western Europe, so as to grasp the movement of weather systems and serve military support.

During the war, the Norwegian school led by Pieknis published the polar front theory in 1922, and their front analysis method and cyclone fluctuation theory made a significant contribution to meteorology, and still plays a guiding role in weather analysis and forecasting today.

It's really good, I just don't know what the hell! I saw several blurry spherical lights here. In the non-stop rotation and sometimes the aggregation sometimes expands the scale, you can't take pictures with your mobile phone at all, you can only see it with the naked eye, it's very mysterious! It took a long time to disappear.

Give the fan blades the same two, and the more you rotate, the bigger it gets. And the speed of rotation is very fast.

Today I also saw four light clusters that were not particularly bright but moved back and forth very quickly.

I just saw (Nanshan, Chongqing), two white sheets, intersecting and rotating back and forth.

I began to see three clouds of light in the sky at eight o'clock in Xiaogan, Hubei Province at eight o'clock this evening, chasing back and forth, one yellow and two blue, and at nine o'clock, it became one yellow and one blue, and when it was almost nine fifty, it was slowly chasing far away, until now it was ten o'clock, I just looked at it and was still there, I thought of a lot of ways to record it, but no matter what mobile phone is used, what is set up and what function, the mobile phone is not visible, the naked eye can see it very clearly, we are here in the countryside, There are no high-rise buildings within fifteen kilometers of the perimeter, and it is impossible to be a searchlight.

I also saw it last night, so I searched it online.

Liaoning Changxing Island yesterday 8 18 I also saw the same, especially magical, with a mobile phone to shoot pixels is not good, can not shoot.

I also saw it when I was in college, in my hometown, on a sunny summer night.
