The Arab station Al Amal has discovered a new type of auroras on Mars, called winding discrete auroras. They are characterized by a large extent and were observed in the ultraviolet wavelength range, according to the mission’s Twitter account.
Sinuous discrete auroras extend for several thousand kilometers, from the day to the night side of Mars, are born in the upper atmosphere and look like long, worm-like structures. Excited atoms of the atmosphere, for example, oxygen, are responsible for their radiation. These auroras were observed during the arrival of solar plasma streams to Mars, which is why the atmosphere was affected by faster and more turbulent flows of solar wind electrons.
