Aurora Borealis is a Northern lights dancing over the sky as they appear. Light it occurs because of the coalition between electrically charged particles from the sun reflecting off particles and gas in Earth’s atmosphere. Aurora lights can be seen in the northern polar region, or in the south polar region. “Aurora Borealis” is another name for the Northern lights in the North Pole, while in the south pole is called the Southern Lights or “Aurora Australis”.
Aurora displays many colors, but the most frequent is the color of light green and pink. Red, yellow, green and blue have appeared several times as well. Light from Aurora reveal assorted forms such as: the beautiful face of a woman, scary faces like monsters, form ribbons, bows, etc.
Aurora Borealis occurs when the coalition between the gas particles in the Earth’s atmosphere, and the electrical particles reflected by the sun. Colorful visible light caused by the type of the gas particles collide. Color chartreuse is the color that is often the most common and emerging, which is produced by oxygen molecules which is located about 97 km (60 miles) from Earth. While other colors that rarely appear, such as red, generated by molecular oxygen from an altitude of 322 km (200 miles). While nitrogen produces blue or purplish red color.
Scientifically, the process of the Aurora rays can be described as follows:
Temperature in the sun’s outer layers ranging in the thousands of degrees Celsius. In this hot temperatures, collisions between gas molecules often occur and cause an explosion. The electrons are liberated as a result of the collision, was thrown from the sun’s atmosphere as the sun rotates. These electrons come out of the holes in the magnetic field of the sun. Then blown by the solar wind to the Earth. Then, the electrified particles deflected by the magnetic field of the earth. In the north and south poles, the strength of the earth’s magnetic field is very weak, and therefore electrically charged particles reflected by barging into the Earth’s atmosphere and collide with gas particles. These collisions produce light that danced in the sky north pole and a south pole.
Light of Aurora is located at a distance of 80 km (50 miles) to 640 km (400 miles) from the Earth’s surface.
Where is the most ideal place to watch the Aurora Borealis?
The Aurora can be seen in the northern hemisphere (Northern Lights / Aurora Borealis) and Southern (Southern Lights / Aurora Australis), centered on the magnetic poles with an irregular oval shape. Because this article deals with Northern lights, then the following list of countries ideal for viewing Northern Lights:
The main requirement to witness the Aurora Borealis is located in a dark location (no light pollution) and sky conditions clear (not cloudy). In Iceland, there are many hotels outside the city which ideal to watch the beautiful phenomenon of the Aurora Borealis. Therefore, it was not surprising that Iceland be the most ideal place and many visited by tourists who hunt Aurora light.
When is the right time to witness the Aurora Borealis?
In Iceland, the tour operators offer package tours to see the Aurora Borealis in from mid September until the end of March each year, or in the winter. Typically, Aurora Borealis began to be seen in August. To monitor the forecasts of Aurora Borealis, you can see this website: http://www.gi.alaska.edu/
Legend of the Aurora Borealis
According to Roman myth, Aurora is the goddess of dawn. In medieval times, the emergence of light Aurora is believed to be a sign of impending war or famine. Maori in New Zealand believe that Aurora is a reflection light from the torches or a bonfire.
Menominee Indian tribe in Wisconsin Americans believes that Aurora light indicates the location of the giants that is the spirit of “hunters and fishermen terrific”. Inuit in Alaska believe that the light of Aurora is the spirit of the animals they hunted, such as seals, salmon, elk and whales. Aborigines believe that the spirits of light Aurora are a collection of members of their community who have died. Residents of Japan and China believe that Aurora light can give the effect of fertility and the smooth process of the birth of their baby.
