The northern lights were visible in Poland last night. This is a phenomenon that rarely occurs in our latitude. We received the photos on Contact 24.

The northern lights are most visible at high latitudes, mainly in the polar regions. On the night from Friday to Saturday, the inhabitants of part of our country also had the opportunity to observe the northern lights. People at the seaside had the best chance of seeing it. The aurora, however, appeared not only in the northern regions, but also in the center.

On Kontakt 24 we received photos of the northern lights seen from the town of Niedźwiady near Kalisz and from Nowe Miasto Lubawskie in the province. Warmia-Masuria Province.

Aurora Borealis visible in Poland

According to the popularizer of astronomy and the author of the blog “With his head in the stars”, “last night, quite unexpectedly, a ‘hole’ in the magnetosphere formed, which caused strong auroras, with not so extreme parameters of the solar wind”. As a result – as he explained – “the northern lights could be seen at latitudes much lower than usual, including in Poland”.

As Wójcicki added, in some places the aurora could be seen with the naked eye.

How the aurora is formed

When viewed from the International Space Station or other orbiting objects, the aurora appears as a glowing green oval around one of Earth’s poles. However, energy builds up in a magnetic field and from time to time is rapidly released into the atmosphere as an electric current. This outburst of CME causes the aurora to turn purple, red and white. These are the outbursts of hot matter into interplanetary space, caused by the rapid expansion of the magnetic field creating loops and arcs in the solar corona.

The flare of the aurora can last from a few to several minutes. When these particles reach Earth, they move along the lines of our planet’s magnetic field. Some of the particles hit the poles, causing the aurora borealis to glow. Others follow an extended “tail” of the magnetic field, which extends away from the sun, that is, in the shadow of the Earth.

As Karol Wójcicki, a promoter of astronomy and author of the blog “Head in the stars”, explains, solar activity increases and decreases in 11-year cycles. Currently, it is in the 25th solar cycle. “When we have maximum solar activity, we see more spots on the disk of our star, there are more active regions and flares. Then more solar matter reaches the earth, which translates directly into the activity of auroras at high latitudes” – he explains. He adds, “Today we are in an advanced introduction phase, or rather, a solid start to the 25th solar cycle.”
