The aurora is display of light. It shape is like curtain. Aurora appear between the sun and the erath rerationship. So it is so far from us. It is higer than flying air plane. Aurora has four colors, red, green, pink and blue. If aurora appeared higest level, it color is red. Middle level is green. Lowest level is pink and blue. And it has two shapes. Aurora do not see anywhere. If you want to see auroras, you have to go the South Pole or the North Pole. And it need clean air and fine weather. So if you saw auroras it is great experience.
In my opinion, we have to know more about nature and serious situation. Then we have to protect nature.
