The co-spin interference region hit Earth’s magnetic field on January 08, 2022, resulting in some of the best aurora borealis lights in the North Pole in years. According to the Jeddah Astronomical Society, regions of co-rotational interference are transitional regions between fast and slow solar wind currents as solar wind plasma accumulates in these regions, resulting in density gradients and shock waves that can rock the Earth’s magnetic field just like coronal mass ejections. (a cloud of ionized gas), which is best in the absence of a real solar storm. The bright colors of the aurora borealis from green to pink are due to the nature of the Earth’s atmosphere, which consists of various gases such as oxygen and nitrogen. When energetic particles coming from the sun hit the atoms and molecules in the atmosphere, those atoms are excited to give off light, different atoms give off different colors, and most importantly, height plays an important role in color. Oxygen at an altitude of regarding 96 km above us gives the familiar yellowish-green light, oxygen at an altitude of regarding 321 km gives a red light, while ionic nitrogen gives a blue light, and natural nitrogen gives a red-violet light, and if the Earth’s atmosphere contains other gases such as neon or gas Sodium, we’ll see red and orange aurora borealis. .
