When do the Northern Lights usually appear?

Auroras are most commonly found in two annular zones near 67° north-south magnetic latitude, known as the Southern Aurora Zone and the Northern Lights Zone. The northern hemisphere is dominated by Alaska, northern Canada, Siberia, Greenland, the southern tip of Iceland and the north coast of Norway. The Southern Hemisphere, on the other hand, is concentrated near Antarctica. It is worth mentioning that:

Alaska and Northern Canada near the North Pole are the best places to see the Northern Lights, and Alaska's Fairbanks have earned the nickname "Northern Lights Capital", with more than 200 days of aurora in a year.

The Northern Lights come in a variety of shapes, some of which are like arcs, some are like cylinders, some are ribbon-shaped, some are shuttle-shaped, and some are like gourds. Some colors are orange-red, some are purple, some are apricot yellow, and some are red, orange, yellow, green, blue, and purple. From the initial appearance to the disappearance, the aurora stays in the air for a long or short period of time, from a few minutes to dozens of minutes.

For example, in 1957, an arc-shaped aurora appeared here for 45 minutes. And in the meantime, it is unpredictable, colorful, colorful and beautiful, and can be described as spectacular.

Mohe County is the best place to observe the Northern Lights in China, so the Mohe County Party Committee and the county ** set the summer solstice as the "Northern Lights Festival". Every year, thousands of tourists from home and abroad gather in the county's Arctic Village to spend a rare white night and look forward to seeing the magical Northern Lights. However, the Northern Lights do not appear every year, and it is understood that most of the local middle-aged and elderly people have seen the Northern Lights, while young people have not seen much.

The Northern Lights are a natural phenomenon that makes them more fantastic than others, so there are many people who want to see them. The time of the aurora is different in different places, but basically the time of the aurora in high latitudes is most obvious from September to April, and it is in full bloom around the summer solstice when the weather is clear.

The Aurora Aurora is an atmospheric luminescence phenomenon unique to the Arctic region, and the aurora itself is found in the north and south poles, because the Antarctic continent is not suitable for observation, so we generally see the Aurora Aurora. In ancient times, people gave the aurora borealis a mystical meaning, and in Norwegian mythology, the aurora was a parade signal for the goddess Aurora. After understanding that the aurora is the interaction between the earth's high-altitude atmosphere and the geomagnetic field and the solar wind, people still give it a beautiful meaning, that is, people who see the aurora will be happy.

When it comes to seeing the aurora, it comes from different places, and Northern Europe is arguably the most suitable place to see the aurora. The aurora occurs every year, and the cycle is long, from September to April of the following year, the best time to see the aurora in Northern Europe is around the spring and autumn equinoxes, if the weather is clear, the moonlight is smaller, because the moonlight before and after the new moon has less impact on the aurora, and the aurora will be more beautiful.

If you want to see the aurora, you can also go to Canada, when it comes to Canada, the most suitable place to see the aurora is the town of Huangdao, which is only 400 kilometers away from the Arctic Circle, where you can see the aurora for two-thirds of the time every year, from August to September, December to April of the following year, every night from 9 o'clock to early morning, the field of vision is broad, and here you can also experience the aurora tent of the Native Americans.

There is also the only place in the country where you can see the Northern Lights - Arctic Village. Located in Mohe City, Heilongjiang Province, Arctic Village is the northernmost town in China, and it is basically polar day around the summer solstice every year, so it is also known as the city that never sleeps. It is also the best time to see the Northern Lights around the summer solstice every year, and the weather is clear on a sunny day, and the sky is clear at night, and the lower part of the night is very suitable for viewing, and during the day, because the sun is too bright, even if the aurora appears, it is difficult to see with the naked eye.

You can see the Northern Lights.

Theoretically, the time is from September to March, with the middle months being the best time to see the Northern Lights. It is difficult to see the aurora during the day, and you only have the opportunity to see it late at night.

Generally speaking, the aurora usually appears from 11 p.m. to 2 a.m., sometimes lasting an hour or two, sometimes in a flash. The 2012-2014 period is the peak of the Northern Lights once in 11 years, and the chances of seeing the Northern Lights are even higher, and the more you travel north, the more likely you are to see them.

The aurora has no fixed form, and the colors are mostly green, white, yellow, and blue, and occasionally it will show a gorgeous reddish-purple, which is graceful and mysterious and unpredictable. The occurrence of the aurora can only be seen in the cold autumn and winter nights, in high latitudes, and the best time is between 10 p.m. and 2 a.m., and sometimes it can last for about 1 hour. Generally speaking, the form of aurora can be divided into four types: arc aurora, ribbon aurora, curtain aurora, and radial aurora.

When the aurora suddenly appears in the sky, sometimes it is just a phantom, like a ghostly color at night. Suddenly, it will expand into a curtain of light, as if pouring down from the depths of the universe. When it is stationary, it can hang still for hours, but when it is excited, it can be like a huge wave.

Tumbling, or like swirling and flying smoke rings. In the colorful places, different colors such as blue, white, red, and green jump together on the pitch-black sky, and the entire sky becomes its performance stage. Sometimes the light is still, sometimes it pours down from the sky like a waterfall, and sometimes it rolls like a huge wave in the dark sky.

The kind of splendor that is not extraordinary has been dazzling since ancient times. No one could help but cheer when they saw it for the first time, and some of them couldn't help but kneel down and pray, and some even fainted with excitement. For thousands of years, this performance from heaven has attracted countless people to look up at the sky.

1. The Northern European aurora generally appears in a few months.

2. The Northern Lights usually appear in a few months.

3. When does the Northern Lights appear.

4. The Northern Lights are only available in months and days.

1.The Northern Lights appear throughout the year, but if you plan to go to Northern Europe to see the Northern Lights, it is best to do so between December and March of the following year, so that the probability of seeing the Northern Lights will be relatively high.

2.In Iceland, from mid-August to mid-April, there is a chance of seeing the Northern Lights for eight months, and the weather is clear and can be observed all over the island.

Analysis: 1) The convergence effect caused by the deflection of the electrons coming from the sun approaching the geomagnetic field and the concentration of the magnetic poles in a spiral. In order to pass through the discharge of the extremely thin and coldest layer of the high atmosphere, it causes a magnificent luminescence phenomenon in the atmosphere.

The shape has arches, bars and mist, etc., and the states range from beating, flickering to **. Auroras are usually white to green, red, yellow, blue, purple or pink in color and last from a few hours to a few days.

2) Why do the auroras only appear at the poles of the earth? It turns out that the earth has a strong magnetic field, and the charged particles from the sun are affected by the earth's magnetic field, due to the effect of the convergence of magnetic field lines, the gas composed of these electrons and positive ions (we call it plasma) will produce an upward electric field along the direction of the earth's magnetic field line, so the electrons in the plasma are accelerated by this electric field and enter the ionosphere at high latitudes, so only the charged particles that shoot into the polar regions can enter the upper atmosphere to produce auroras.

3) The geomagnetic north pole is in Canada (the geomagnetic north pole is about 1200km away from the geographical north pole. The two are intersected by the center of the earth. Therefore, aurora is common in southern Canada and the northern United States, and is rarely seen in the low magnetic latitudes of Siberian volta.

The Northern Lights can usually only be seen at higher magnetic latitudes, but can be seen at slightly lower magnetic latitudes when solar storms are intense. Scientists have been able to correctly ** the 11-year cycle of solar storms, a large number of charged particles from the solar storm rush to the earth, and interact with the geomagnetic field to produce the gorgeous scenery of the Northern Lights. The second millennium AD coincided with the peak of the 11-year cycle, which can also be seen at slightly lower magnetic latitudes.

4) The one located at the North Pole is called the Northern Lights, and the one located at the South Pole is called the South Lights, just like the halo on the head of an angel, set in the night sky of the North and South Poles of the earth. The Northern Lights and Southern Lights can sometimes appear in pairs like images in a mirror.
