A streak of blood-red light, almost like a demonic arc or river of blood flowing across the sky, caused confusion among many people in Scandinavia. Scientists confirm that it is not an aurora.
According to the sheet Spacethe sequence is described as a The river of light is as red as bloodfaint, stretching across the night sky, seen in some places as an arc like a rainbow but with only one color.
The phenomenon appeared last week, coinciding with the strongest geomagnetic storm hitting Earth in 6 years. On the American side, a pink light also appeared, believed to be a strange type of aurora. However, a new analysis confirms The “river of blood” observed from Northern Europe is not the Aurora Borealis.

According to the analysis of scientists Space weather. com, This unusual phenomenon is called “stable auroral red arc” (SAR)and despite the name – which may have been given by the first misconceptions about this type of phenomenon – it is not an aurora and is not necessarily stable.
The ghostly “River of Blood”. is light emitted by oxygen molecules in the upper atmosphere and heated by Earth’s circular current system, a giant ring of electrical current surrounding the planet.
Geomagnetic storms appeared and created a polar eclipse. During this aurora, high-energy particles from the solar wind and the ball of plasma it ejects into the Earth’s magnetosphere excite gas molecules in the upper atmosphere, causing various phenomena, including solar flares. Swirling light of all colors is caused by different types of atoms being excited.
For the SAR, what is interesting is oxygen, Heated by the electric current surrounding this magnetosphere, it glows like an aurora but has a frightening red color.
The SAR observed in Northern Europe – most clearly in Denmark – is not the only unusual light show observed during the recent giant storm. A STEVE-like phenomenon – a band of purple light that is also not an aurora borealis – is also hovering over the skies of the US and UK.
