If these aurora lights are about 300 kilometers high they will probably be red. This is very unusual but can happen when there are solar winds to the maximum. The most common colors are yellow and green. All of these lights are called by oxygen, but these are all at lower altitudes. Nitrogen at about 100 kilometers high produces red aurora lights.Violent ExplosionsThese explosions very because the sun has a cycle from about to eleven years. The sun can sometimes throw out some things called coronal mass ejection or in easier terms CME. If these hit the earth there can be some massive auroras which can lead to massive impressions in the sky which every one just has too see. They can even be seen from England to the artic because they are so strong. But this rarely happens.What Causes Auroras?Auroras are caused by high energy particles from the solar wind that are trapped in the Earth's magnetic field. As these particles go back and forth along the magnetic field lines, they come down into the atmosphere near the north and south magnetic poles where the magnetic field lines disappear into the body of the Earth.

The sun Essay

693 words - 3 pages grid failure, communication difficulties and unusual auroras. Example of the Sun's sunspot activity causing power grid failure is that of 1989, where a geomagnetic storm caused one of the transformers in the power transmission grid of hydro Quebec in Canada to fail. This event precipitated the collapse of the entire power grid. Despite this, the sun also contributes positively to such technologies such as solar panels.In conclusion the Sun affects the Earth life, the environment and technology in both positive and negative ways. However, life would not exist without the sun to power it.
