It all started on Thursday, when there was a big solar flare in the Sun. As the portal explained imeteo.sk, The sun is currently in its 11-year cycle, which means that it is becoming more and more active. Until about 202 to 2025, the eruptions on this star, which is essential for our lives, should increase.
One of the stronger eruptions also occurred on the aforementioned Thursday, when a cloud of coronal plasma was ejected and headed for Earth. Thus, two conditions were met in order to be able to observe the aurora borealis. It is this cloud that can cause a geomagnetic storm, which means for us that we can observe aurora borealis in the sky.
However, as it turns out, this cloud only hit us marginally – so the big theater in the night sky did not take place. At least as far as our territory is concerned. However, it was possible to observe the incredible play of light from the northern parts of Europe. Around midnight, social networks were literally flooded with photographs from Scotland, Scandinavia, Russia, Greenland and Iceland, capturing a beautifully lit sky.
We may still see
However, there is still hope that the aurora borealis will still be observed on the northern horizon by people in Slovakia. That could happen tonight. There is also the possibility in the game that what caused yesterday’s aurora borealis in the north of Europe was just a kind of vanguard and the arrival of coronal mass after Thursday’s eruption was delayed than expected.
However, its visibility can also be affected by factors such as moon brightness or light smog. Therefore, the predictions have already pointed out in advance that if polar demand occurs in our country, it will be possible to observe it especially in mountainous areas.
