Dancing light. This is the spectacle that some French people are witnessing this Sunday evening, November 5, 2023. The Northern Lights were observed from 7 p.m. The phenomenon is still visible in places around 9 p.m. The fleeting spectacle has already been immortalized by several people who share photos of their observations on social networks.

Countries other than France are spoiled by this beautiful entertainment: the Northern Lights are widely admired, especially in Europe in Slovakia, Poland, in Ukraine Or in Sweden.
What is the origin of these northern lights observed in France?
The auroras observed on the evening of November 5th could have come from a filament that was “torn” on the Sun that same day. in the morning. “The arrival of a wave of solar particles this night is causing at this very moment (Sunday evening) a geomagnetic storm and the formation of an aurora borealis visible from France.” written down the scientific mediator Pierre Henriquet about X.
To see the Northern Lights, it is recommended to look at the sky towards the north.
How is the Aurora Borealis formed?
The Northern Lights, a type of aurora borealis (along with the Southern Lights), is a light phenomenon that occurs in the Earth’s atmosphere. The origin of the northern lights is the sun, or more precisely the solar wind. This stream of particles, constantly emitted by the star’s atmosphere, brings electrons and protons with it.
A small portion of these particles that arrive on Earth are directed to our planet’s magnetic poles. The particles collide with gases in Earth’s upper atmosphere and fill the sky with shimmering colors. The observed hues (pink, red, green, blue, purple) depend on various parameters, including the altitudes at which particle collisions occur.
