THE AURORA BOREALIS.

Aurora Borealis is a phenomenon made by nature that is vibrant and colorful. Researchers discovered that the auroral activity is cyclic, peaking roughly every 11 years. Nothing that man has created comes even close to these mind blowing lights that every person who is aware of it wants to see its magnificent at least once in their life time.
The bright dancing lights of the aurora are actually collisions between gaseous particles in the Earth's atmosphere with electrically charged particles released from the sun's atmosphere that enter and spark as a result of it. Variation in color are due to the type of gas particles that are colliding. The most common auroral color is a pale yellowish-green produced by high-altitude oxygen, at heights up to 200 miles. Nitrogen produces blue or purplish-red aurora.
The temperature above the surface of the sun is millions of degrees Celsius. At this temperature, collisions between gas molecules are frequent and explosive. Free electrons and protons are thrown from the sun's atmosphere by the rotation of the sun and escape through holes in the magnetic field. Being blown towards the earth by the solar wind, the charged particles are largely deflected by the earth's magnetic field. However, the earth's magnetic field is weaker at either pole and therefore many particles enter the earth's atmosphere through that points and collide with gas particles in it, emitting lights that we perceive as the dancing light of the aurora.
The lights are seen above the magnetic poles of the Northern and Southern hemispheres. They are known as Aurora Borealis in the North, meaning "dawn of the north," and Arora Australis in the South, meaning "dawn of the south." In Roman myths, Aurora was the goddess of the dawn and mother of winds, who announced the arrival of the sun each morning by racing her chariot across the sky. The people who live in the North of the Arctic Circle has its own explanation. They said that the lights were energies created by the soul of the departed and whoever disrespected them  would experience bad fortune, such as sickness or even death. Also they said that the sparks had magical effects and by using shaman drums they could harness the effect of the spark's energy.
The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow, and generally extend from 80 km (50 mi) to as high as 640 km (400 mi) above the earth's surface in east-west direction.
Areas that are not subject to light pollution are the best places to watch the aurora. Winter in the North is generally a good season to view the lights. The long period of darkness an the frequency of clear nights provide many good opportunities to watch the auroral displays. Yukon, Northwest Territories and Alaska are the best spots in the North, while the southern auroras are concentrated in a ring around Antarctica and the southern Indian Ocean.
An historical significance had an event that occurred due to the great geomagnetism storm occurred on both August 28 and September 2nd of 1859. It was the most spectacular ever witnessed throughout that specific generation of people. It was the result of an exceptionally intense white light solar flare produced by an aurora so wide spread and extraordinary brilliant that they were seen and reported in published scientific measurements, ship's logs and newspapers throughout the United States, Europe, Japan and Australia. It was said in the New York Times' newspaper that "ordinary print could be read by the light of the aurora." The aurora is thought to have been produced by one of the most intense coronal mass ejections during that time, very near to the maximum intensity that the sun is thought to be capable of producing according to human mind estimation of its power. This was the first time that the people in power over the earth at that time got the first lesson of the connection where the phenomena of auroral activity and electricity were linked. The insight was made possible not only due to scientific magnetometer measurements of the era but also as a result of a significant portion of the 125,000 miles of telegraph lines then in service being significantly disrupted for so many hours throughout the storm.
Some telegraph lines however, seem to have been of the appropriate length and orientation which allowed a geo-magnetically induced current to be induced in them due to Earth's severely fluctuating magnetosphere and actually be used for communication. Two operators of the Telegraph Line were able to maintain a conversation for around two hours using no battery power at all and working solely with the current induced by the aurora, giving them, for the first time in their life, a lesson from Nature, many words were transmitted by the power of it and not by the human power.
