- People generally know the aurora borealis by their common name, the Northern Lights. The northern lights are natural phenomena that occur in nature. Often on a clear, dark night in the boreal forest, green, purple, pink, and white lights dance on the horizon changing their shape and color. It is perhaps one of nature™s most fascinating displays of artistry. Specifically, the aurora borealis is Latin for ﬁnorthern dawn.ﬂ The aurora australis is the same phemonena in the southern hemisphere, most visible from Antarctica, Australia, and New Zealand.

Aurora Borealis (Northern Lights) Aurora Borealis (Northern Lights) Weather.gov > Sioux Falls, SD > Aurora Borealis (Northern Lights) The Aurora Borealis (commonly referred to as the Northern Lights) are the result of interactions between the Sun and Earth's outer atmosphere. The Aurora Australis is the southern hemisphere counterpart to the Aurora Borealis.

- Rings around the Poles. The electrons that create auroras start in the outer layers of the field, where it is compressed by the solar wind. They accelerate along the field lines, converging toward the magnetic poles from all directions. This results in an oval ring around each magnetic pole where auroras occur. The north pole aurora is called the aurora borealis and the aurora at the south pole is called the aurora australis.

How are the colors of the aurora created? The color of the aurora depends on the wavelength of the light emitted. This is determined by the specific atmospheric gas and its electrical state, and the energy of the particle that hits the atmospheric gas. The atmosphere consists mainly of nitrogen and oxygen, which emit the characteristic colors of their respective line spectra.

How does the aurora borealis (the Northern Lights) work? ­As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from 20 to 200 miles above the earth's surface. The color of the aurora depends on which atom is struck, and the altitude of the meeting. 1  Green-oxygen, up to 150 miles in altitude.2  Red-oxygen, above 150 miles in altitude. 3  Blue-nitrogen, up to 60 miles in altitude.As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from 20 to 200 miles above the earth's surface.

This is determined by the specific atmospheric gas and its electrical state, and the energy of the particle that hits the atmospheric gas.he atmosphere consists mainly of nitrogen and oxygen, which emit the characteristic colors of their respective line spectra. Atomic oxygen is responsible for the two main colors of green (wavelength of 557.7 nm) and red (630.0 nm). Nitrogen causes blue and deep red hues.

How Aurora Borealis is formed? Aurora borealis occurs in the layer of the atmosphere called the  Thermosphere. Ionized particles from the sun are drawn to the  magnetic poles of Earth, which gives us the … spectacular Northern  Lights.

- Northern and Southern lights. An Aurora is a natural electric phenomenon that creates bright and colorful light displays in the skies. Auroral light displays are common at higher latitudes, and most auroral activity generally occurs within the Arctic and the Antarctic Circles.

Auroras that occur in the Arctic Circle are known as aurora borealis or northern lights, while auroras in the antarctic circle are known as aurora australis or southern lights.

What do auroras look like? Originating in an atmospheric layer high above the surface of the Earth, auroras are generally seen at altitudes between 100 km and 500km. They are most frequently seen in the auroral ovals, which are two rough circles centered on the magnetic poles of the Earth with a diameter of about 3000 km.

How does the aurora borealis (the Northern Lights) work? The auroras, both surrounding the north magnetic pole (aurora borealis) and south magnetic pole (aurora australis) occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about 1 million miles per hour.As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from 20 to 200 miles above the earth's surface. The color of the aurora depends on which atom is struck, and the altitude of the meeting. 1  Green-oxygen, up to 150 miles in altitude.

- The color of the aurora depends on which gas is being excited by the electrons and on how much energy is being exchanged. Oxygen emits either a greenish-yellow light (the most familiar color of the aurora) or a red light; nitrogen generally gives off a blue light. The oxygen and nitrogen molecules

They are common at higher latitudes, mostly within the Arctic and the Antarctic Circles. Aurora borealis in Michigan, USA. The northern lights can be green, pink, red, blue or violet in color. ©iStockphoto.com/Constance McGuire. In the Arctic Circle, they are known as aurora borealis or the northern lights, while in the Antarctic Circle they are called aurora australis or the southern lights. These dramatic and colorful lights are created when electrically charged particles from solar winds enter the Earth’s atmosphere and interact with gases in the atmosphere.

Northern Lights The Northern Lights look somewhat similar to a sunset in the sky at night, but appear occasionally in arcs or spirals usually following the earth's magnetic field. They fairly often look like moving curtains of light, high in the sky. They are most often light green in color but often have a hint of pink.

What Causes the Aurora Borealis Colors? The aurora australis or Southern Lights are seen in the southern hemisphere. The light you see comes from photons released by oxygen and nitrogen in the upper atmosphere. Energetic particles from the solar wind strike the layer of the atmosphere called the ionosphere, ionizing the atoms and molecules.

An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.t is visible from high southern latitudes in Antarctica, South America, New Zealand, and Australia. Auroras also occur on other planets. Similar to the Earth's aurora, they are also visible close to the planets’ magnetic poles.

How are the colors of the aurora created? The sun radiates all visible colors, which is why sunlight appears white. The spectrum of visible light associated with the aurora is much more restricted. The aurora is caused by charged particles in the solar wind colliding with atmospheric atoms and ions.

Aurora Borealis AURORAS OCCUR along ring-shaped regions around the north and south geomagnetic poles. Fairbanks, Alaska, is a good place for Aurora watching because it is under this region in the north, where people see Aurora Borealis, or northern lights; the southern Aurora is Aurora Australis.airbanks, Alaska, is a good place for Aurora watching because it is under this region in the north, where people see Aurora Borealis, or northern lights; the southern Aurora is Aurora Australis.

- What We See. Auroras form in rings centered over the Earth's magnetic poles. During an aurora, rings form around the North and South poles at the same time. Even near the poles, someone on Earth can only see a tiny section of the auroral oval. Look at the satellite image of the aurora borealis to the left.

Aurora Borealis Forecast for Thursday, April 05, 2018 REAL TIME AURORA FORECAST MAP. It's helpful to get confirmation of activity with NOAA's Ovation map. The Kp number gives nice info on how large the storm is, but the Ovation map does a better job of telling you if you can actually see it. It gives a 20 to 40 minute forecast of the predicted size of the aurora along with a color-coded probability of seeing the aurora over various spots on the Earth. Here is the most up-to-date image: It's a good sign if you see a thick aurora band with some areas of light yellow, orange or, better yet, RED on this map as opposed to just a thin (or transparent) band with only dark green.

Two big solar storms have hit Earth â creating stunning auroras and a few disruptions Nighttime auroras will also be visible in the northern US. On the upside, geomagnetic storms can also create brightly colored auroras in the skies. According to AccuWeather, people in northern states from Oregon to Maine may be able to see the nighttime show on Friday night (and possibly several evenings thereafter):
