Pretty sure it's the aurora borealis
The brilliant light displays that occur in the Ionosphere are called the auroras, specifically the northern lights (aurora borealis) in the northern hemisphere and the southern lights (aurora australis) in the southern hemisphere. These light displays are caused by charged particles from the Sun interacting with Earth's magnetic field and colliding with particles in the Earth's atmosphere.
The brilliant light displays in the ionosphere are known as the Aurora, which includes the Aurora Borealis in the Northern Hemisphere and the Aurora Australis in the Southern Hemisphere. These displays are caused by charged particles from the sun colliding with particles in Earth's atmosphere, producing glowing lights. They are primarily visible in polar regions and during periods of heightened solar activity.
