Good morning, friends of steemit, this is a very short and simplified article at the limit of my limited capacity on this subject; Surely one of the most impressive natural spectacles are the aurora borealis.

The auroras are glows in the sky that appear at the time of sunrise or sunset in polar latitudes.
Scientifically according to http://gatubelyta-universe.blogspot.com/2007/04/aurora-boreal.html, a northern aurora occurs when a set of solar mass, which arrives in the form of dust, collides with the north and south poles Of the Earth's magnetosphere, and produces a diffuse but predominant light projected into the Earth's ionosphere.

The variety of colors, red, green, blue and violet that appear in the sky, are product of the different gases of the ionosphere. The Aurora Borealis is in constant change due to the variation of the interaction between the solar wind and the magnetic field of the earth. The solar wind normally generates more than 100,000 megawatts of electricity when it produces an aurora and this can cause interference with power lines, radio and television broadcasts and satellite communications. Through the study of auroras, scientists can learn more about the solar wind, how it affects our atmosphere and how auroral energy could be used for useful purposes.

Aid to hunt the northern lights
The beautiful flares of northern lights or Aurora Borealis appear when material thrown from the surface of the sun collides with the Earth's atmosphere. Thus, by following the events of the solar star and the velocity of the gaseous substances coming from its surface, we can predict the occurrence of aurora borealis with a great degree of precision or enough to satisfy the needs of the average observer of the sky night. These predictions and observations are referred to in the style of weather forecasts as "spatial time".

The auroras appear on the polar regions of the earth in what are called aurora ovals. In the northern hemisphere, the aurora oval protrudes farther south, the stronger the solar wind at any given time. The oval normally extends over northern Finland and Scandinavia, all of Canada, the northern United States, Alaska and Siberia. In the case of a solar storm, I would go farther south, being able to reach as far as the skies of Central Europe. Because the oval does not extend symmetrically over the rotational axis of the earth, each degree of earth length turns deeper into the oval once every 24 hours. In the case of Finland, this rotation means that the best time to see the aurora borealis would be around 22.30 (Stardard time). On the other hand, it is worth bearing in mind that a solar storm can appear at any time of the day or night and therefore it might be advisable to the hunters of wonderful shows that concentrate on following different types of predictions and forecasts Are published on the Internet.

Now they can dedicate themselves to seeing the beautiful colors of the aurora (live if they are lucky, in photo if they are like me, far from the poles) the same physics is valid in our earth as in the rest of the universe; It is not so bad, since only that simple thing allows us to understand nature and marvel at the spectacle of light that it produces.
Here some photos of this beautiful phenomenon:
