Most auroras occur 90---130 kilometers above the Earth. But some aurora lights are much higher. In 1959, a Northern Lights measured at an altitude of 160 kilometers and a width of more than 4,800 kilometers.
City lights and tall buildings on the horizon can get in the way, so the best sights of the aurora can only be seen in the open areas of the countryside. In Churchill City, Canada, the Northern Lights can be seen on 300 nights a year; In the state of Lurida, on average, it can only be seen about 4 times a year. Mohe, the northernmost part of my country, is also a good place for the aurora.
In the mid-18th century, scientists at a Swedish geophysical observatory discovered that when the observatory observed the aurora, the hands of the compass on the ground would change irregularly by as much as 1 degree. At the same time, a similar phenomenon was recorded at the Geomagnetic Observatory in London. From this, they believe that the appearance of auroras is related to changes in the geomagnetic field.
It turns out that the aurora is the result of the interaction of the solar wind with the Earth's magnetic field. The solar wind is a charged particle ejected by the sun, and when it blows above the earth, it is affected by the earth's magnetic field. The Earth's magnetic field is shaped like a funnel, with the tip facing the north and south poles of the Earth, so the charged particles emitted by the Sun follow the Earth's magnetic field"Funnels"Settle, entering the polar regions of the Earth.
The upper atmosphere of the poles glows when bombarded by the solar wind, forming auroras. The upper atmosphere is composed of a variety of gases, and the front color of the light emitted by the bombardment of the gases of different elements is different. For example, oxygen emits green and red light when excited, nitrogen emits purple light when excited, and blue light when argon is excited, so the aurora is gorgeous and varied.

Auroras are basically only available in the South Pole and the North Pole, and whether the drift is beautiful depends on luck, whether you can meet a beautiful one.

Auroras generally occur at high latitudes, and can be seen at the South and North Poles around the world. However, for now, people usually go to the North Pole to see the Northern Lights, because there are still places where there is human activity. The first choice to see the aurora is Alaska in the United States, and from November to March of the following year, many aurora lovers will go in groups.
The subject doesn't have to worry too much about not seeing the aurora, because Alaska can see the aurora two-thirds of the time of the year. The aurora is more likely to be green and single-colored, and if you want to see the gorgeous ones, it depends on your luck. Remember to keep warm, it's cold over there.

Arctic VillageIt is the only best place to observe the Northern Lights in China. Arctic Village is located inDaxinganling area, Heilongjiang ProvinceMohe Township, Mohe City, is the best place to observe the Northern Lights in China and the northernmost town in China.
Arctic Village is not only an ancient town with a long history, it has formed a symbol and a coordinate. Many people come here every year from all over the world for sightseeing, especially around the summer solstice. Because the sky is often clear around the summer solstice and the moonlit nights in late autumn, it is the best time to see the Northern Lights.
In Mohe, the aurora will crack all year round, and there are many shapes of the aurora, including strips, fans, sheets, etc., and the color is also red and orange.
Yellow, green, green and other colors are intertwined with distinct colors and colors, and the scenery is still spectacular. If you don't see the aurora in Jiqing, it's also good to feel the most beautiful galaxy. The starry sky of Mohe is also known as the most beautiful starry sky, as long as you look up, you can see the starry sky, the beautiful starry sky, sitting on a high place and stretching out your hand as if you can touch the starry sky.
The beauty of Mohe is unique in China, with the aurora in the sky, the snowfields on the ground, and the swaying birch forests.
The clean air, everything here does not seem to have changed because of human beings, and this is different from the Jiangnan water town of Xiaoqiao and flowing water.
The land here, the sky here, and the simple people who live here hold up the word "atmosphere".

High latitudes.
There are records of the discovery of the aurora in the northern part of Heilongjiang in China.
Mohe is recommended to go to Canada, Norway.
Aurora Aurora
It often occurs in the atmosphere at latitudes close to the geomagnetic poles. It is generally banded, arc-shaped, curtain-shaped, or radial. These shapes are sometimes stable and sometimes continuous.
Auroras are produced by the excitation or ionization of molecules or atoms in the upper atmosphere by a stream of charged energetic particles (up to 10 kiloelectron volts) from the sun's active region. Due to the geomagnetic field, these energetic particles are turned to the polar regions, so auroras are commonly found in high magnetic latitudes. Auroras often occur in the range of about 25° to 30° from the magnetic pole, and this area is called the aurora zone.
The region between 60° and 45° of the geomagnetic latitude is called the weak aurora zone, and the area of the geomagnetic latitude below 45° is called the micro aurora zone. The height of the lower bound of the aurora is less than 100 kilometers above the ground, the height of the maximum luminous point is about 110 kilometers, the normal maximum boundary is about 300 kilometers, and in extreme cases it can reach more than 1,000 kilometers. According to recent studies on the distribution of auroras, the shape of the polar trapped spike region is not a ring centered on the geomagnetic pole, but more like an oval.
The spectral line range of the aurora is about 3100 to 6700 angstroms. One of the most important spectral lines is the 5577 angstroms atomic oxygen green line, called the aurora green line. The occurrence of auroras is related to magnetic storms, the geocorona, the solar wind and cosmic rays, and therefore to solar activity.
As early as more than 2,000 years ago, China began to observe the upgrading of auroras, and since then there have been abundant aurora records.

Aurora, you can definitely see it in the Arctic and Antarctic circles. However, in the Mohe River of Heilongjiang in my country, you can already see it, and you don't have to go to the Arctic Circle.
