A luminous phenomenon caused by the collision of atoms in the high altitude and upper atmosphere near the poles.
Zhu Jin pointed out that although auroras are common in areas with high magnetic latitudes, if the geomagnetic storm is particularly strong, the range of aurora occurrence will expand, so it is indeed possible to see auroras in the Beijing area at 40° north latitude.
