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 our country also had the opportunity to observe it. People at the seaside had the greatest chance to admire this phenomenon. 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
As the astronomer of astronomy and author of the blog “With his head in the stars” Karol Wójcicki “admits, last night, quite unexpectedly, a” gap “in the magnetosphere formed, which caused strong auroras, with not so extreme parameters of the solar wind”. As a result – he explained – “the northern lights could be seen at latitudes much lower than usual, including in Poland”.
Wójcicki added that in some places the aurora could be seen with the naked eye. The observation was favored by the clear or even cloudless sky.
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.
Solar activity increases and decreases in cycles over 11 years. Currently, it is in the 25th solar cycle. As Wójcicki informs, “when we have the maximum solar activity, we see more spots on the disk of our star, there are more active regions and flares. More solar matter then reaches the earth, which translates directly into the activity of auroras at high latitudes” – he explains. As he emphasizes, “today we are in an advanced introduction phase, or rather, a solid start to the 25th solar cycle.”
