When did you see the aurora in the northern hemisphere?

Question 1: When and where can I see the aurora? It is the best time to watch the aurora in Mohe from summer to around 9 days every year, which is a rare natural phenomenon in the polar regions of the earth. Because Mohe is located in the northern hemisphere with high latitude, the aurora appearing in Mohe is the aurora emitted by the North Pole of the earth, and the aurora seen in Mohe is called the Northern Lights. Aurora is very common in the polar regions of the earth, but people don't see many opportunities. Although the Northern Lights appear many times, people seldom see them. The reason is that when the aurora is produced, the location where the aurora occurs and the observation location of the aurora, as well as between the two places, are often blocked by cloudy weather and rarely seen. Mohe is the only best place to observe the Northern Lights in China, which is a blessing from nature to Mohe people. Although the Northern Lights appear all year round, it is easy to see in Mohe, only in the summer to around 9 days every year. Due to the clear sky around Wan Li from summer solstice, people can see the spectacular Northern Lights when there is no cloud barrier between the Arctic and Mohe. The northern lights come in many shapes. When Mohe appeared, people saw stripes, ribbons, umbrellas, fans, flakes, gourds, shuttles, cylinders, spheres and so on. The colors of the Northern Lights are red, orange, yellow, green, cyan, blue and purple, with distinct colors. From the first rise to the disappearance, the period is unpredictable and colorful. Observing the aurora in Mohe should be carried out not only in the summer to 9 days before and after each year, but also at night. Even if the aurora appears during the day, it is not easy to be found because of the high brightness of the sun and the low brightness of the aurora. Because Mohe is located on the high latitude line, the extreme day phenomenon of white night will appear every summer, which provides favorable conditions for viewing the aurora.

Question 2: When is the best season to see the aurora? Aurora is likely to be seen all year round. You must find a good destination to see the aurora. Aurora observation points in the northern hemisphere are mainly Alaska, northern Canada, Siberia, Greenland, the southern tip of Iceland and the northern coast of Norway. The southern hemisphere is concentrated near Antarctica, such as Argentina.

It is suggested to go to northern Europe to see the aurora in winter, such as Finland, Sweden, Denmark and Norway. In northern Europe in winter, there is extreme sunlight, so it is easier to observe the aurora. For more tourist information about Aurora, please check here: dwz/Wuerzhilv.

Question 3: Which country first saw the aurora in the northern hemisphere? Greenland, a dependency of Denmark.

Question 4: When is the best season to see the Northern Lights? The formation of northern lights

The word "aurora" comes from the Latin Ios. Legend has it that Ios is the incarnation of "Dawn" in Greek mythology, the daughter of the Greek god Titan and the sister of the sun god and the moon goddess.

When humans first looked up at the sky and saw the Northern Lights, the Northern Lights were always a "mystery". For a long time, people have developed their own aurora legends. Eskimos believe that "Aurora is a torch for ghosts and gods to guide the souls of the dead to heaven". The aborigines, on the other hand, regard "aurora as the appearance of gods, and think that the fast-moving aurora will make the gods trample on the empty voice, take away people's souls and leave bad luck".

For a long time, the cause of aurora has been debated endlessly. Some people think that it is a fire burning at the outer edge of the earth; Some people think it is light reflected from the sky after sunset; Others believe that it is an energy released by polar ice and snow at night after absorbing and storing sunlight during the day. It was not until man sent a satellite rocket into space that the mystery of this celestial phenomenon was explained physically.

Aurora is essentially an optical phenomenon excited by the operation of atoms and molecules in the uppermost layer of the earth's atmosphere (above the ground 100-200 km). It consists of three elements: the sun, the wind, the earth's magnetic field and the atmosphere. The so-called "solar wind" is an energy that the sun constantly radiates to the universe. It consists of electrons and protons. Due to the intense activity of the sun, countless charged particles are emitted. When charged particles flow to the earth and enter the range of the earth's magnetic field, they will enter the upper atmosphere near the north and south magnetic poles at high speed along the earth's magnetic field lines, and collide with particles such as oxygen atoms and nitrogen molecules, resulting in "electromagnetic storms" and "visible light" phenomena, which become a striking "aurora".

Probability of aurora appearance

Aurora is most common in two circular belts near the north-south magnetic latitude of 67, which are called the Southern Aurora and the Northern Aurora respectively. The northern hemisphere is dominated by Alaska, northern Canada, Siberia, Greenland, the southern tip of Iceland and the northern coast of Norway; The southern hemisphere is concentrated near Antarctica. It is worth mentioning that Alaska and northern Canada, which are near the North Pole, are the best places to watch the aurora, and fairbanks, Alaska, has won the reputation of "Northern Lights Capital", with more than 200 days of aurora in a year.

The shape of the aurora changes instantly.

Aurora is a natural astronomical wonder. It has no fixed pattern and different colors. The colors are mostly green, white, yellow and blue, and occasionally they show gorgeous red and purple, graceful and mysterious. Aurora can only be seen in cold autumn and winter nights and high latitudes. The best time is from 10 in the afternoon to 2 am, and sometimes it lasts about 1 hour.

Generally speaking, there are four types of aurora: arc aurora, ribbon aurora, curtain aurora and radial aurora. What appears in the north is called the Northern Lights, and what appears in the south is called the Southern Lights.

If you have the chance to go to Alaska, you must go to see the charming Northern Lights, capture the ever-changing super "electro-optic show", and you will completely fall in love with the Northern Lights!

For a long time, people have been eager to understand and explore the mystery of aurora. In the last century, people used cameras, video cameras and satellites to clearly see and understand the discharge phenomenon caused by the collision between solar energy and the earth's magnetic field. It is a river of electron light, releasing one million megawatts of light in the sky 60 miles away from the earth. In an unscientific era, people can describe this wonderful natural scenery as long as they use their infinite imagination, so there are many mysterious legends handed down from ancient times. The origin of the name of the Northern Lights is that the scientist Cassidy called this phenomenon "Aurora" after repeated consideration. She is the goddess of weaving in ancient Roman mythology, representing the dawn before sunrise. Bekele, a scientist, believes that electrons emitted by the sun fly freely in space. When they break into the earth's magnetic field, electrons collide with gas and emit light. This is the Northern Lights. His theory was not proved until 60 years later. Scientists first proved that the earth has two magnetic fields after the launch of American rocket 14. A year later, Harbor 2 first measured the plasma of the sun (the charged substance that constitutes the solar airflow), and the solar airflow can touch the earth. Solar airflow is also called solar wind. These radiations rushed to the earth at a speed of 3 million kilometers. Fortunately, the earth's magnetic field changed the direction of the solar wind and protected us from it. When the solar wind collides with the earth's magnetic field, it will generate 654.38+000 trillion yuan of energy, small particles in the earth's atmosphere will release energy, oxygen atoms will emit green light or red light, and the oxygen content will be >>

Question 5: When the Aurora Borealis appears is a natural astronomical wonder. It has no fixed pattern and different colors. The colors are mostly green, white, yellow and blue, and occasionally they show gorgeous red and purple, graceful and mysterious. Aurora can only be seen in cold autumn and winter nights and high latitudes. The best time is from 10 in the afternoon to 2 am, and sometimes it lasts about 1 hour.
