Aurora Borealis and Aurora Australis

The Aurora Borealis and the Aurora Australis, sometimes called The Northern and Southern Lights, are natural light displays in the sky, usually observed at night, particularly in the polar regions. Auroras are most visible closer to the Poles due to the longer periods of darkness and the magnetic field.

Can you see Northern lights in Copenhagen?

While it's rare to see the Northern Lights in Copenhagen due to its southern location and light pollution, it is occasionally possible during periods of high solar activity. Ideal conditions would include a clear, dark sky away from city lights. For a better chance of witnessing the auroras, you might consider traveling further north in Denmark or to neighboring countries like Sweden or Norway.

What is a black aurora?

A black aurora is a type of aurora that exists at the top of the ionosphere, where electrons flow upward into space (unlike normal aurora, which involve downward flowing electrons), leaving deep cavities in the atmosphere, making blank spaces when regular aurora are seen, hence being "black" or non-luminous, but having the shape of aurora.

What is northern lights poles?

The northern lights are in the northern hemisphere hence nearer the north pole.

What causes aurora borealis and Aurora Australis?

Do aurora australis seen here in the Philippines?

yes . my friend says that she see aurora australis here in the philippines

but im not sure :)

How do the northern lights affect people?

Other than impressing them with their beauty and inspiring them to awe - the northern lights really don't have any effect on people.

The solar radiation that causes the northern lights can interfere with radio transmissions so that is an effect related to, but not cause by, the northern lights.

Can you find northern lights in the antarctic?

No. What you see there are the Southern Lights, which are caused in the same way, so in effect they are the same thing.

Another Answer

The confusion may be in the names. In the north, these lights are called Aurora Borealis, and in the South, Aurora Australis.

What causes the auroras borealis?

Auroras are caused by radiation from the sun, called solar wind, interacting with Earth's magnetic field. When magnetic storms occur on the Sun, electrically charged particles (ions) from the corona and solar flares are added to the solar wind produced by the corona. Solar charged particles from the sun, which are normally radiated into space, sometimes get caught in the Earths magnetic field as they come into the upper atmosphere they react with other gases and produce coloured lights.

The Earth's magnetic field funnels particles from the solar wind over the polar regions (due to the magnetic nature of the Earth). The charged particles are accelerated by the Earth's magnetic field and interact with the gases in the upper atmosphere and cause the gas molecules to emit light. Electrons in the molecules are excited to higher energy levels by the accelerated charged particles and the electrons release photons when they fall back to lower energy levels.

When the ions from the sun first collide with air particles more than 80 kilometres above the ground, each causes a different reaction, and each reaction causes a different color to explode. Collisions of these particles with atmospheric molecules causes energy emission as visible light. Neutral nitrogen particles will create a purplish pink color, while ionic nitrogen transforms into a brilliant blue. If an ion crashes into oxygen in a lower altitude, it becomes the most common aurora, a yellowish-green color. If it however, collides with oxygen at a high level, it will create the rarest blood red aurora. An aurora is sometimes accompanied by a crackling sound. Auroras can occur on other planets.

Can a solar flare cause an Aurora Borealis on earth?

Yes, a solar flare can contribute to the occurrence of an Aurora Borealis (Northern Lights) on Earth. Solar flares release bursts of solar energy and charged particles into space, which can interact with the Earth's magnetic field. When these charged particles collide with gases in the Earth's atmosphere, they excite those gases and cause them to emit light, resulting in the beautiful displays of the aurora. However, it's important to note that auroras are primarily driven by coronal mass ejections (CMEs) rather than solar flares alone.

Is it possible to predict the northern lights?

Yes, but not very long in advance. When there is a lot of activity on the surface of the sun and it ejects material towards Earth, the Northern Lights can be seen. So if the activity on the Sun is seen, then it is possible to predict that the Northern Lights will be seen in the following hours and days.

Can you see aurora borealis from the Aleutian Islands?

When the Aurora Borealis happen, they can be seen from the Aleutian Islands.

Is the Aurora Borealis?

The aurora is a glow observed in the night sky, usually in the polar zone.

For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as "aurora borealis" which is Latin for "northern dawn" since in Europe especially, it often appears as a reddish glow on the northern horizon as if the sun were rising from an unusual direction.

The aurora borealis is also called the "northern lights". The aurora borealis most often occurs from September to October and March to April. Its southern counterpart, "aurora australis", has similar properties.

The cause of the aurora is charged particles from the solar wind, accelerated by the Earth's magnetic field, colliding with atoms in the upper atmosphere causing them to glow as they release their surplus energy.

What are the chances you'll see an aurora once while standing in your backyard?

That will depend on things like where in the world you are and how clear a view of the sky you have and weather conditions along with other factors.

How do auroras appear in the night sky?

Auroras appears in the night sky by atoms and molecules. Auroras is lights in the sky.

What auroras produced by?

Auroras are produced by interactions among thermospheric gases and free electrons

Where in the northern hemisphere is the aurora or northern lights most often found?

The aurora borealis, or northern lights, is most commonly found in the polar regions of the northern hemisphere, particularly within an area known as the "Auroral Oval." This oval typically extends across countries such as Norway, Sweden, Finland, Canada, and Alaska. The lights are most visible during winter months when nights are longer and skies are darker. Additionally, solar activity can enhance visibility, making certain periods more favorable for viewing.
